Description

Polarizing plate-integrated window substrate and manufacturing method therefor {WINDOW SUBSTRATE COMBINED WITH POLARIZING PLATE AND PREPARING METHOD THEREOF}

The present invention relates to a polarizing plate integrated window substrate and a method of manufacturing the same.

Due to the development of the information society, display devices capable of displaying information have been actively developed. The display device includes a liquid crystal display device, an organic electro-luminescence display device, a plasma display panel, and a field emission display device.

Among them, an organic light emitting display device is a self-luminous display that emits light by electrically exciting a fluorescent organic compound. This organic light emitting display device can be driven at a low voltage and has advantages such as thinness.

Such an organic light emitting display displays an image using light generated from an organic light emitting diode (OLED). When light is introduced from the outside, the light is sequentially incident on the polarizing plate and the phase film and the organic light emitting diode (OLED). Is reflected again by the electrode part which comprises). The light reflected back by the electrode constituting the organic light emitting diode (OLED) causes problems such as glare when the user looks at the organic light emitting display.

In addition, a method of preventing a user from feeling glare by blocking light reflected by an electrode unit using a polarizing film has been proposed.

Recently, studies on flexible displays that are thinner, lighter, and more flexible than conventional panels using polymer films instead of glass substrates are being actively conducted. Therefore, although a touch sensor pattern or the like is formed on a conventional glass substrate, it is being replaced by a film material due to a limitation in that it cannot implement flexible characteristics. The most problematic problem in the flexible display is the thickness of the entire display panel. As the thickness increases, the impact that the panel bends increases, which increases the possibility of breakage. Therefore, the thickness of each element constituting the display panel is also a key goal.

In the organic light emitting display device, a polarizing plate is used to block reflected light. The polarizing plate has a polarizer and a protective film attached to both sides thereof, and thus a total of three films are used, and thus the display panel becomes thick in its entirety. There is.

Hereinafter, preferred examples are provided to aid the understanding of the present invention, but these examples are merely illustrative of the present invention and are not intended to limit the scope of the appended claims, which are within the scope and spirit of the present invention. It is apparent to those skilled in the art that various changes and modifications can be made to the present invention, and such modifications and changes belong to the appended claims.

The polarizing plate-integrated window substrate of the present invention includes a base substrate 100, a non-display portion pattern 200 positioned on a non-display portion of one surface of the base substrate 100, and a liquid crystal polarization layer 300 positioned on the display portion of the same surface.

The base substrate 100 may be applied to a liquid crystal display, a touch screen panel, and the like, and may be a material that is durable enough to sufficiently protect them from external forces and allows a user to see the display well. Substrate 100 can be used without particular limitation. For example, glass, polyethersulphone (PES), polyacrylate (PAR, polyacrylate), polyetherimide (PEI), polyethylene naphthalate (PEN, polyethyelenen napthalate), polyethylene terephthalate (PET, polyethyelene terepthalate, polyphenylene sulfide (PPS), polyallylate, polyimide, polycarbonate (PC, polycarbonate), cellulose triacetate (TAC), cellulose acetate propionate (cellulose acetate propionate (CAP) may be used.

The thickness of the base substrate 100 is not particularly limited, and may be, for example, 10 to 200 μm. If the thickness is less than 10 μm, it may be difficult to implement sufficient hardness, strength, and the like as the window substrate. If the thickness is more than 200 μm, the overall thickness increases, making it difficult to implement the thin film weight.

The base substrate 100 includes a display unit for displaying an image when applied to an image display device or the like, and a non-display unit that is not covered by the non-display unit pattern 200 that forms part of the housing of the electronic device. For example, an image may be output from the non-display unit, but the image displayed on the non-display unit is hidden by the non-display unit pattern 200 so that the user cannot see it.

The non-display portion pattern 200 is positioned on the non-display portion of one surface of the base substrate 100.

The non-display portion pattern 200 forms a boundary between the display portion and the non-display portion and prevents the lower wiring or the like from being viewed by the user as the light blocking pattern.

A conventional polarizing plate-integrated window substrate that uses the liquid crystal polarization layer 300 instead of the polarizing plate for thinning has a non-display portion pattern 200 formed on the non-display portion on the liquid crystal polarization layer 300 and the liquid crystal polarization layer 300 coated on one surface thereof. ). Thus, when applied to an image display device or the like, light incident on the non-display portion pattern 200 from the display panel is visually recognized by the user through the liquid crystal polarization layer 300, thereby preventing color visibility of the non-display portion pattern 200. .

However, since the non-display portion pattern 200 according to the present invention is directly in contact with the base substrate 100, light incident from the display panel to the non-display portion pattern 200 is visually recognized by the user without passing through the liquid crystal polarization layer 300. By forming the non-display unit pattern 200 in various colors, the user may visually recognize the non-display unit pattern 200 in various colors.

The non-display portion 200 according to the present invention may be a single layer or a multilayer.

The single layer non-display portion 200 is a light blocking pattern having a color to be implemented.

The non-display portion 200 of the multilayer may be formed by stacking a light blocking pattern having a color to be implemented in multiple layers.

In addition, the multi-layered non-display portion pattern 200 may include a first pattern 210 forming a boundary between the display portion and the non-display portion, and a second light blocking pattern 220 covering the non-display portion where the first pattern 210 is positioned. It may include.

The first pattern 210 forms a boundary between the display unit and the non-display unit. The first pattern 210 may be positioned only at an edge of the display unit and the non-display unit, or may be located in the entire non-display unit.

The first pattern 210 may be transparent or opaque. Even if the first pattern 210 is transparent, since the second pattern 220 is light-shielding, the second pattern 220 may prevent the lower wiring from being viewed by the user.

The second pattern 220 is a light blocking pattern covering the non-display portion where the first pattern 210 is located.

The first pattern 210 and the second pattern 220 may be a single layer or a multilayer pattern independently of each other.

When the first pattern 210 or the second pattern 220 is a multi-layered pattern, each layer may be transparent or opaque independently of each other. However, at least one of the second patterns 220 is opaque.

The thickness of the non-display portion 200 is not particularly limited, and may be, for example, 1 to 100 μm. It is preferable that the non-display portion pattern 200 have a thickness greater than or equal to that of the liquid crystal polarization layer 300 in view of manufacturing processes.

In the non-display portion 200, patterns such as icons, IRs, and logos may be engraved.

The liquid crystal polarization layer 300 is positioned on the display unit on the same plane as the non-display unit pattern 200.

A conventional polarizing plate is made of a polarizer and a protective film attached to both surfaces thereof, but the liquid crystal polarizing layer 300 has an advantage of significantly reducing the thickness by using it as a coating layer serving as a polarizer.

The liquid crystal polarization layer 300 includes the liquid crystal layer 320 and the alignment layer 310, and may be formed by aligning the liquid crystal layer 320 by the alignment treatment 310.

The liquid crystal polarization layer 300 is positioned on the display unit, and as described above, light incident to the non-display unit pattern 200 from the display panel is visually recognized by the user without passing through the liquid crystal polarization layer 300, so that the user may have various colors. The non-display part pattern 200 may be visually recognized.

The thickness of the liquid crystal polarization layer 300 is not particularly limited, and may be, for example, 1 μm to 30 μm. If the thickness is less than 1 μm, the adhesion of the liquid crystal polarization layer 300 to the base substrate 100 may be insufficient. If the thickness is greater than 30 μm, the entire thickness of the polarizing plate-integrated window substrate is increased, making it difficult to implement a thin film of an image display apparatus. have.

The polarizing plate integrated window substrate of the present invention may further include a phase difference layer 400 disposed on the liquid crystal polarization layer 300.

The retardation layer 400 may be a coating layer or a film.

The retardation layer 400 may be a single layer or a multilayer, and may be a quarter wave plate in the case of a single layer, and may be a multilayer of a quarter wave plate and a half wave plate in the case of a multilayer, but are not limited thereto. In the case of multiple layers of a quarter wave plate and a half wave plate, the color and image quality are excellent when applied to an image display device by phase difference correction.

The thickness of the retardation layer 400 is not particularly limited, and may be, for example, 1 μm to 100 μm. If the thickness is less than 1 μm, the phase characteristics may be deteriorated. If the thickness is more than 100 μm, the thickness of the entire polarizing plate-integrated window substrate is increased, which makes it difficult to implement a thin film of the image display apparatus.

In addition, the polarizing plate-integrated window substrate of the present invention may further include a refractive index adjusting layer 500 located on the retardation layer 400.

The refractive index adjusting layer 500 adjusts the refractive index to improve color and the like when applied to an image display device.

The refractive index adjusting layer 500 may be a coating layer or a film. For example, C-PLATE of a stretched film method or a liquid crystal coating method can be used.

The thickness of the refractive index adjusting layer 500 is not particularly limited, and may be, for example, 1 μm to 30 μm. If the thickness is less than 1 μm, the phase characteristics may be deteriorated. If the thickness is more than 30 μm, the thickness of the entire polarizing plate-integrated window substrate is increased, which makes it difficult to implement a thin film of the image display apparatus.

The present invention also provides an optical laminate including the polarizing plate integrated window substrate.

The optical laminate of the present invention includes the polarizing plate integrated window substrate and a touch sensor attached thereto.

The touch sensor may be attached to the side of the non-display portion pattern 200 and the liquid crystal polarization layer 300 on the window substrate.

The touch sensor may be attached using an aqueous, photocurable adhesive or pressure sensitive adhesive known in the art.

The touch sensor may be used without limitation including those known in the art, such as a base film, a sensing electrode layer, an insulating layer, and a passivation layer.

The present invention also provides an image display device including the optical laminate.

The optical laminated body of the present invention can be applied to various image display devices such as electroluminescent display devices, plasma display devices, field emission display devices, as well as ordinary liquid crystal display devices.

The present invention also provides a method of manufacturing the polarizing plate integrated window substrate.

According to the exemplary embodiment of the manufacturing method of the polarizing plate-integrated window substrate of the present invention, first, a non-display part pattern 200 is formed on one surface of the base substrate 100 to partition the display part and the non-display part.

The base substrate 100 may be applied to a liquid crystal display, a touch screen panel, and the like, and may be a material that is durable enough to sufficiently protect them from external forces and allows a user to see the display well. Substrate 100 can be used without particular limitation. For example, glass, polyethersulphone (PES), polyacrylate (PAR, polyacrylate), polyetherimide (PEI), polyethylene naphthalate (PEN, polyethyelenen napthalate), polyethylene terephthalate (PET, polyethyelene terepthalate, polyphenylene sulfide (PPS), polyallylate, polyimide, polycarbonate (PC, polycarbonate), cellulose triacetate (TAC), cellulose acetate propionate (cellulose acetate propionate (CAP) may be used.

The thickness of the base substrate 100 is not particularly limited, and may be, for example, 10 to 200 μm. If the thickness is less than 10 μm, it may be difficult to implement sufficient hardness, strength, and the like as the window substrate. If the thickness is more than 200 μm, the overall thickness increases, making it difficult to implement the thin film weight.

The base substrate 100 includes a display unit for displaying an image when applied to an image display device or the like, and a non-display unit that is not covered by the non-display unit pattern 200 that forms part of the housing of the electronic device. For example, an image may be output from the non-display unit, but the image displayed on the non-display unit is hidden by the non-display unit pattern 200 so that the user cannot see it.

The method of forming the non-display portion pattern 200 is not particularly limited, and any method may be used as long as the pattern can be formed by an embossing method. For example, physical vapor deposition, chemical vapor deposition, plasma deposition, plasma polymerization, thermal deposition, thermal oxidation, anodic oxidation, cluster ion beam deposition, slit coating, knife coating, spin coating, casting, microgravure coating, gravure Coating method, bar coating method, roll coating method, wire bar coating method, dip coating method, spray coating method, screen printing method, gravure printing method, flexographic printing method, offset printing method, inkjet coating method, dispenser printing method, nozzle And coating methods, capillary coating methods, and the like.

Forming the non-display portion pattern 200 may include forming a first pattern 210 that divides the display portion and the non-display portion; And forming a light blocking second pattern 220 covering the non-display portion where the first pattern 210 is positioned.

The first pattern 210 forms a boundary between the display unit and the non-display unit. The first pattern 210 may be positioned only at an edge of the display unit and the non-display unit, or may be located in the entire non-display unit.

The first pattern 210 may be transparent or opaque. Since the second pattern 220 is light-shielding, there is no problem in preventing the lower wiring from being viewed even if transparent.

The second pattern 220 is a light blocking pattern covering the non-display portion where the first pattern 210 is located.

The first pattern 210 and the second pattern 220 may be a single layer or a multilayer pattern independently of each other.

When the first pattern 210 or the second pattern 220 is a multi-layered pattern, each layer may be transparent or opaque independently of each other. However, at least one of the second patterns 220 is opaque.

The thickness of the non-display portion pattern 200 is not particularly limited, and may be, for example, 1 to 100 μm. The non-display portion pattern 200 may have a thickness greater than or equal to that of the liquid crystal polarization layer 300 in that the coating layer does not pass to the non-display portion when the liquid crystal polarization layer 300 is formed by coating.

Thereafter, as shown in FIG. 4C, the liquid crystal polarization layer 300 is formed on the display portion partitioned by the non-display portion pattern 200.

Forming the liquid crystal polarization layer 300 may include coating and aligning the alignment layer 310; Coating a liquid crystal layer (320) on the alignment-treated alignment layer (310); And curing the liquid crystal layer 320.

The coating method of the alignment layer 310 and the liquid crystal layer 320 is not particularly limited, and for example, the slit coating method, knife coating method, spin coating method, casting method, micro gravure coating method, gravure coating method, bar coating method, Roll coating method, wire bar coating method, dip coating method, spray coating method, screen printing method, gravure printing method, flexographic printing method, offset printing method, inkjet coating method, dispenser printing method, nozzle coating method, capillary coating method, etc. The method can be mentioned.

The alignment treatment of the alignment layer 310 may be performed by, for example, rubbing the alignment layer 310 with a rubbing roll, but is not limited thereto, and may be performed by a method known in the art.

The coated liquid crystal layer 320 may be cured using UV or heat.

The thickness of the liquid crystal polarization layer 300 is not particularly limited, and may be, for example, 1 μm to 30 μm. If the thickness is less than 1 μm, the adhesion of the liquid crystal polarization layer 300 to the base substrate 100 may be insufficient. If the thickness is greater than 30 μm, the entire thickness of the polarizing plate-integrated window substrate is increased, making it difficult to implement a thin film of an image display apparatus. have.

Since the display portion and the non-display portion are already partitioned by the non-display portion pattern 200, when the liquid crystal polarization layer 300 is formed by coating, the material does not fall to the non-display portion, thereby preventing material loss and liquid crystal polarization. The layer 300 can be easily formed only in the display portion.

If necessary, the method of manufacturing a polarizing plate-integrated window substrate of the present invention may further include attaching a release film 700 covering the non-display portion before the liquid crystal polarization layer 300 is formed.

In such a case, the release film 700 may cover the non-display portion to prevent the liquid crystal polarization layer 300 from flowing over to the non-display portion more efficiently.

The release film 700 may be cut to have an opening in the display unit so that the liquid crystal polarization layer 300 may be formed in the display unit, or may be formed by cutting after the release film 700 is attached.

More specifically, the release film 700 may be attached before the alignment layer formation 310 of the liquid crystal polarization layer 300, or after the alignment layer 310 is formed and before the polarization layer 320 is formed.

In the case of multiple layers of a quarter wave plate and a half wave plate, the color and image quality are excellent when applied to an image display device by phase difference correction.

The thickness of the retardation layer 400 is not particularly limited, and may be, for example, 1 μm to 100 μm. If the thickness is less than 1 μm, the phase characteristics may be deteriorated. If the thickness is more than 100 μm, the thickness of the entire polarizing plate-integrated window substrate increases, which makes it difficult to implement a thin film of the image display apparatus.

In addition, the method of manufacturing a polarizing plate integrated window substrate of the present invention may further include forming a refractive index adjusting layer 500 on the retardation layer 400.

The refractive index adjusting layer 500 may be formed by coating the refractive index adjusting layer 500 on the retardation layer 400 or by attaching a refractive index adjusting film.

The thickness of the refractive index adjusting layer 500 is not particularly limited, and may be, for example, 1 μm to 30 μm. If the thickness is less than 1 μm, the phase characteristics may be deteriorated. If the thickness is more than 30 μm, the thickness of the entire polarizing plate-integrated window substrate is increased, which makes it difficult to implement a thin film of the image display apparatus.
