It may also be possible if the horizontal prism sheet 620 is disposed.

The reflective polarizing film 600 may be referred to as a dual brightness enhancement film (DBEF). The reflective polarizing film 600 may selectively transmit light or reflect light according to the wavelength of light. Through this process, light of a predetermined wavelength is passed and light of other wavelengths is reflected, thereby reducing the amount of light blocked in the polarizing film disposed on the display panel 100, thereby improving luminance.

The vertical / horizontal prism sheets 610 and 620 may improve the luminance of an image displayed on the display panel 100 by adjusting a light propagation path so that incident light is directed toward the display panel 100.

In addition, as in the case of FIG. 19B, the reflective polarizing film 600 includes a core layer 601, a first protective layer 602 positioned on a first surface of the core layer 601, and The second protective layer 603 may be disposed on the second surface of the core layer 601.

In addition, the optical layer 110 in a horizontal direction (first direction DRH or second direction DRV) may include a portion spaced apart from the support film 400 by a predetermined distance D1. For example, the reflective polarizing film 600 of the optical layer 110 in the horizontal directions DRH and DRV may include a portion spaced apart from the support film 400 by a predetermined distance D1.

Alternatively, the reflective polarizing film 600 may be attached to the rear polarizing film 3410. In addition, the support film 400 may be attached to the reflective polarizing film 600.

For example, as shown in FIG. 20, the first surface of the core layer 601 of the reflective polarizing film 600 is attached to the rear polarizing film 3410, and faces the first surface of the core layer 601. The supporting film 400 may be attached to the second surface.

83 to 95 are views for explaining the optical layer in more detail. In the following, description of the parts described above in detail will be omitted. In the present invention, the arrangement order of the optical sheets constituting the optical layer may be variously changed.

At least a first optical sheet of the plurality of optical sheets constituting the optical layer includes an opening, and at least a second optical sheet of the remaining optical sheets other than the first optical sheet of the plurality of optical sheets is a protrusion corresponding to the opening. It may include. In this case, the first optical sheet and the second optical sheet may be engaged and fixed.

For example, as shown in FIG. 83, a protrusion 630PA may be formed in the diffusion plate 630 of the optical sheet unit, and an opening 600H may be formed in the reflective polarizing film 600. Here, the reflective polarizing film 600 may correspond to the first optical sheet, and the diffusion plate 630 may correspond to the second optical sheet.

In more detail, the reflective polarizing film 600 is horizontal from the body portion 600B and the body portion 600B extending in the horizontal direction (the first direction DRH and / or the second direction DRV). It may include an extension port 600E extending in the vertical direction DRZ crossing the directions DRH and DRV. Here, the horizontal directions DRH and DRV and the vertical direction DRZ may be perpendicular to each other.

In addition, an opening 600H may be formed in the extension 600E.

The diffusion plate 630 may have a body portion 630B extending in the first direction DRH and a protrusion 630PA extending in the first direction DRH from the body portion 630B.

Here, the projection 630P can penetrate through the opening 600H as in the case of FIG. 84.

In addition, as in the case of FIG. 84, the thickness Z10 of the diffusion plate 630 on which the protrusion 630PA is formed is the thickness Z11 of the reflective polarizing film 600 on which the extension 600E and the opening 600H are formed. Can be greater than In detail, the thickness Z10 of the body portion 630B of the diffusion plate 630 may be greater than the thickness Z11 of the body portion 600B of the reflective polarizing film 600. This is because the thinner the sheet, the easier the extension and the opening are formed.

Preferably, at least the thinnest optical sheet of the plurality of optical sheets included in the optical layer 110 may include an extension and an opening.

In the present invention, the third optical sheet disposed in the first optical sheet and the second optical sheet of the plurality of optical sheets of the optical layer 110 has a body portion extending in the first direction DRH, the second direction from the body portion ( And an opening defined by the extension.

For example, as in FIG. 85, the diffusion plate 630 of the optical layer 110 includes a protrusion 630PA, and includes a vertical prism sheet 610, a horizontal prism sheet 620, and a reflective polarizing film ( 600 may include body portions 610B, 620B, 600B, extensions 610E, 620E, 600E and openings 610H, 620H, 600H, respectively. Here, since the structures of the vertical prism sheet 610 and the horizontal prism sheet 620 can be sufficiently inferred from the description of FIG. 83, the detailed description thereof will be omitted.

Here, the vertical prism sheet 610 and the horizontal prism sheet 620 may correspond to the third optical sheet. Hereinafter, unless otherwise mentioned, the vertical prism sheet 610 and the horizontal prism sheet 620 are collectively referred to as a prism sheet PSL.

Referring to FIG. 85, the openings 610H and 620H of the prism sheet PSL may overlap with the opening 600H of the reflective polarizing film 600.

In this case, as shown in FIG. 86, the protrusion 630PA of the diffusion plate 630 may penetrate through the openings 610H and 620H of the prism sheet PSL and the opening 600H of the reflective polarizing film 600. have.

Here, considering that the thinner the sheet is, the easier it is to form the openings and the extension, the thickness Z10 of the diffusion plate 630 is the thickness Z11 of the reflective polarizing film 600, as in the case of FIG. The thickness Z12 of the vertical prism sheet 610 may be greater than the thickness Z13 of the horizontal prism sheet 620. In detail, the thickness Z10 of the body portion 630B of the diffusion plate 630 is the thickness Z11 of the body portion 600B of the reflective polarizing film 600, and the body portion 610B of the vertical prism sheet 610. ) May be greater than the thickness Z12 and the thickness Z13 of the body portion 620B of the horizontal prism sheet 620.

In addition, as in the case of FIG. 87, when the opening 600H of the reflective polarizing film 600, the opening 610H of the vertical prism sheet 610, and the opening 620H of the horizontal prism sheet 620 overlap each other. The width P13 of the reflective polarizing film 600 is greater than the width P12 of the vertical prism sheet 610 in the horizontal directions DRH and DRV by the thicknesses of the extensions 600E, 610E, and 620E. The width P12 of the vertical prism sheet 610 may be larger than the width P11 of the horizontal prism sheet 620.

In detail, the width P13 of the body portion 600B of the reflective polarizing film 600 in the horizontal directions DRH and DRV is larger than the width P12 of the body portion 610B of the vertical prism sheet 610. The width P12 of the body portion 610B of the vertical prism sheet 610 may be larger than the width P11 of the body portion 620B of the horizontal prism sheet 620.

On the other hand, the size of the opening may vary according to the stacking order of the plurality of optical sheets. For example, when the third optical sheet having the opening is disposed between the second optical sheet having the projection and the first optical sheet having the opening, the opening of the first optical sheet is larger than the opening of the third optical sheet. Or may be the same.

For example, as in the case of Figure 88, (C) the size of the opening 600H of the reflective polarizing film 600 is (B) larger than the size of the opening 610H of the vertical prism sheet 610, (B The size of the opening 610H of the vertical prism sheet 610 may be larger than the opening 620H of the (A) horizontal prism sheet 620.

In this case, the projection 630P of the diffusion plate 630 is an opening 620H of the horizontal prism sheet 620, an opening 610H of the vertical prism sheet 610, and an opening 600H of the reflective polarizing film 600. Can be easily penetrated in turn.

Meanwhile, at least one hole may be formed between the body part and the extension part of the at least one optical sheet. In detail, at least one hole is formed at a boundary between the at least one body part and the extension part, and the part where the hole is formed is bent to distinguish the extension part and the body part.

For example, as shown in FIG. 89A, an extension part 600E extending from the body part 600B of the reflective polarizing film 600 in the horizontal direction DRH and DRV is formed, and the extension part ( The opening 600H can be formed in 600E.

Thereafter, as in the case of FIG. 89B, a plurality of holes 600HP may be formed at the boundary between the body portion 600B and the extension portion 600E.

Subsequently, as shown in FIG. 89C, the boundary between the extension part 600E and the body part 600B may be bent such that the extension part 600E extends from the body part 600B in the vertical direction DRV. have.

As such, at least one hole 600HP formed between the extension 600E and the body 600B may help to bend the extension 600E.

Meanwhile, the diffusion plate 630 may include a plurality of sheets. For example, as in the case of FIG. 90, the diffusion plate 630 may include a first diffusion plate 631 and a second diffusion plate 632. Here, the thickness Z60 of the first diffusion plate 631 may be different from the thickness Z61 of the second diffusion plate 632. Although the thickness Z60 of the first diffusion plate 631 is shown to be thicker than the thickness Z61 of the second diffusion plate 632 here, the thickness Z61 of the second diffusion plate 632 is the first diffusion. It may also be possible to be thicker than the thickness Z60 of the plate 631. Alternatively, the thickness Z60 of the first diffusion plate 631 and the thickness Z61 of the second diffusion plate 632 may be substantially the same.

Referring to FIG. 91, protrusions 632P may be formed on the second diffusion plate 632, and protrusions may not be formed on the first diffusion plate 631.

In this case, the protrusion 632P of the second diffusion plate 632 may correspond to the openings 610H and 620H of the prism sheet PSL and the opening 600H of the reflective polarizing film 600.

In addition, the first diffusion plate 631 may be simply mounted on the second diffusion plate 632.

In this case, the optical sheet portion can have the same shape as in the case of FIG. Here, for ease of the process of forming the protrusions, the thickness Z14 of the first diffusion plate 631 in which the protrusions are not formed may be thicker than the thickness Z10 of the second diffusion plate 632 including the protrusions 632P. Can be.

Referring to FIG. 92, at least one end of the extension 600E of the reflective polarizing film 600, the extension 610E of the vertical prism sheet 610, and the extension 620E of the horizontal prism sheet 620 may be formed. It may be located on the side of the first diffusion plate 631. In this case, separation of the first diffusion plate 631 can be prevented.

As such, at least one end of the extension 600E of the reflective polarizing film 600, the extension 610E of the vertical prism sheet 610, and the extension 620E of the horizontal prism sheet 620 is first diffused. The length Z72 of the extension 600E of the reflective polarizing film 600, the length Z71 of the extension 610E of the vertical prism sheet 610, and the horizontal to be positioned on the side of the plate 631. At least one of the length Z70 of the extension portion 620E of the prism sheet 620 is larger than the thickness Z10 of the second diffusion plate 632 and the thickness Z14 of the first diffusion plate 631 and the second diffusion. It may be desirable to be smaller than the sum Z10 + Z14 of the thickness Z10 of the plate 632.

This configuration is expressed differently as follows.

The first optical sheet, the third optical sheet, the second optical sheet, and the fourth optical sheet are sequentially disposed, wherein the first optical sheet is disposed on the display panel 100 side, and the fourth optical sheet is disposed on the rear cover ( 130, the first and third optical sheets include extensions and openings, the second optical sheet includes protrusions, and the fourth optical sheet does not include protrusions.

In this case, the thickness of the fourth optical sheet may be thicker than the thickness of the first, second, and third optical sheets.

In this case, the ends of the extension of the first optical sheet and the extension of the third optical sheet may be located on the side of the fourth optical sheet. In addition, at least one of the length of the extension of the first optical sheet and the length of the extension of the third optical sheet is greater than the thickness of the second optical sheet and less than the sum of the thickness of the second optical sheet and the thickness of the fourth optical sheet. May be the same.

Here, the first optical sheet may correspond to the reflective polarizing film 600, the third optical sheet may correspond to the prism sheet PSL, and the second optical sheet corresponds to the second diffuser plate 632. The fourth optical sheet may correspond to the first diffuser plate 631.

Alternatively, when the first optical sheet, the third optical sheet, and the second optical sheet are disposed in this order, the first optical sheet includes an extension and an opening, and the second optical sheet includes a protrusion. The third optical sheet positioned between the second optical sheet and the second optical sheet may include a protrusion.

For example, as in the case of FIG. 93, the vertical prism sheet 610 and the horizontal prism sheet 620 as well as the second diffusion plate 632 may include protrusions 610PA and 620PA.

In addition, as in the case of FIG. 94, the projection 632P of the second diffusion plate 632, the projection 610P of the vertical prism sheet 610, and the projection 620P of the horizontal prism sheet 620 are reflective polarizing films. It can penetrate through the opening 600H of 600.

In this case, as in the case of FIG. 95, the body portion 632B of the second diffusion plate 632, the body portion 610B of the vertical prism sheet 610, and the body portion 620B of the horizontal prism sheet 620. The lengths P30 may be approximately equal to each other.
