請參照第1圖，其繪示根據本發明第一實施例之顯示面板1之一基板10之一側的剖視圖。顯示面板1可包括數個畫素單元(或可稱為一子畫素單元)，此些畫素單元可呈陣列形式排列成一畫素陣列。在第1圖中，僅繪示出三個畫素單元P1、P2、P3。可理解的是，在圖面未示出的地方(包括沿X軸和Y軸延伸的方向)還可包括其它畫素單元。 Please refer to FIG. 1, which illustrates a cross-sectional view of one side of a substrate 10 of a display panel 1 according to a first embodiment of the present invention. The display panel 1 may include a plurality of pixel units (or may be referred to as a sub-pixel unit), and these pixel units may be arranged in an array to form a pixel array. In Fig. 1, only three pixel units P1, P2, and P3 are shown. It can be understood that other pixel units may be included in places not shown in the drawing (including directions extending along the X-axis and Y-axis).
本實施例中，基板10為靠近觀看者(例如：人眼)之一側。舉例來說，圖面所示之Z軸正方向的視角，可為觀看者觀看顯示面板1時之視角。進一步地說，基板10可以是彩色濾光基板或其它種相似類型之基板。 In this embodiment, the substrate 10 is close to one side of a viewer (for example, human eyes). For example, the viewing angle in the positive direction of the Z axis shown in the figure may be the viewing angle when the viewer views the display panel 1. Further, the substrate 10 may be a color filter substrate or other similar types of substrates.
當基板10為彩色濾光基板時，顯示面板1可包括一黑色矩陣層11以及一彩色濾光層12。黑色矩陣層11和彩色濾光層 12設置於基板10的內表面。彩色濾光層12可包括數個彩色濾光單元。黑色矩陣層11可具有數個開口(未標示)，每一個彩色濾光單元可設置於一對應的開口中，例如可一對一地設置於開口中。在第1圖中，僅繪示出三個彩色濾光單元12R、12G、12B。可理解的是，在圖面未示出的地方(包括沿X軸和Y軸延伸的方向)還可包括其它彩色濾光單元。每一個彩色濾光單元12R、12G、12B各對應於一個畫素單元P1、P2、P3，例如可一對一地對應於畫素單元P1、P2、P3。舉例而言，如第1圖所示，彩色濾光單元12R對應於畫素單元P1，彩色濾光單元12G對應於畫素單元P2，彩色濾光單元12B對應於畫素單元P3。 When the substrate 10 is a color filter substrate, the display panel 1 may include a black matrix layer 11 and a color filter layer 12. Black matrix layer 11 and color filter layer 12 is disposed on an inner surface of the substrate 10. The color filter layer 12 may include a plurality of color filter units. The black matrix layer 11 may have a plurality of openings (not labeled), and each color filter unit may be disposed in a corresponding opening, for example, may be disposed one by one in the openings. In FIG. 1, only three color filter units 12R, 12G, and 12B are shown. It can be understood that other color filter units may be included in places not shown in the drawing (including directions extending along the X-axis and Y-axis). Each of the color filter units 12R, 12G, and 12B corresponds to one pixel unit P1, P2, and P3, and may correspond to the pixel units P1, P2, and P3 one-to-one, for example. For example, as shown in FIG. 1, the color filter unit 12R corresponds to the pixel unit P1, the color filter unit 12G corresponds to the pixel unit P2, and the color filter unit 12B corresponds to the pixel unit P3.
顯示面板1可包括一顏色轉換層13，顏色轉換層13位於基板10上。進一步地說，顏色轉換層13位於黑色矩陣層11和彩色濾光層12上。換句話說，黑色矩陣層11和彩色濾光層12(或各彩色濾光單元12R、12G、12B)位於基板10與顏色轉換層13之間。 The display panel 1 may include a color conversion layer 13, and the color conversion layer 13 is located on the substrate 10. Further, the color conversion layer 13 is located on the black matrix layer 11 and the color filter layer 12. In other words, the black matrix layer 11 and the color filter layer 12 (or each of the color filter units 12R, 12G, and 12B) are located between the substrate 10 and the color conversion layer 13.
顏色轉換層13可以是多孔材料，但本發明不以此為限。顏色轉換層13可例如是螢光體材料，螢光體材料例如包括多個釔鋁石榴石(Yttrium Aluminum Garnet,YAG)螢光粉131和多個黏著劑132混合的物質。在其它實施例中，顏色轉換層13可為螢光染料(fluorescence dye)、量子點(quantum dot,QD)材料、其它合適的波長轉換材料或其組合。但本發明不以上述材料為限。 The color conversion layer 13 may be a porous material, but the invention is not limited thereto. The color conversion layer 13 may be, for example, a phosphor material. The phosphor material includes, for example, a mixture of a plurality of Yttrium Aluminum Garnet (YAG) phosphors 131 and a plurality of adhesives 132. In other embodiments, the color conversion layer 13 may be a fluorescent dye, a quantum dot (QD) material, other suitable wavelength conversion materials, or a combination thereof. However, the present invention is not limited to the above materials.
顯示面板1可更包括一保護層14。保護層14覆蓋顏色轉換層13，藉以保護顏色轉換層13。保護層14包括數個圖案化保護單元14U，每一個圖案化保護單元14U各對應於一個畫素單元P1、P2、P3，例如可一對一地對應於畫素單元P1、P2、P3。當顏色轉換層13為多孔材料的情況下，這些圖案化保護單元14U更填充於顏色轉換層13的孔隙中。 The display panel 1 may further include a protective layer 14. The protective layer 14 covers the color conversion layer 13, thereby protecting the color conversion layer 13. The protective layer 14 includes a plurality of patterned protection units 14U, and each of the patterned protection units 14U corresponds to one pixel unit P1, P2, P3, for example, one-to-one correspondence with the pixel units P1, P2, P3. When the color conversion layer 13 is a porous material, these patterned protection units 14U are further filled in the pores of the color conversion layer 13.
保護層14的材料可為有機絕緣材料、無機絕緣材料或其組合。舉例而言，有機絕緣材料可為聚醯亞胺(polyimide,PI)、聚醯胺酸(polyamic acid,PAA)、聚醯胺(polyamide,PA)、聚乙烯醇(polyvinyl alcohol,PVA)、聚乙烯肉桂酸酯(polyvinyl cinnamate,PVCi)、聚甲基丙烯酸甲酯(polymethyl methacrylate,PMMA)、其它適合的光阻材料或其組合。無機絕緣材料可為氧化矽、氮化矽、氮氧化矽、矽氧烷或其它適合的絕緣材料。但本發明不以上述材料為限。舉例而言，在一實施例中，保護層14可以是透明的材料。在其它實施例中，保護層14也可以是在透明材料中摻雜有螢光染料、量子點材料、YAG螢光粉、其它合適的波長轉換材料或其組合。 The material of the protective layer 14 may be an organic insulating material, an inorganic insulating material, or a combination thereof. For example, the organic insulating material may be polyimide (PI), polyamic acid (PAA), polyamide (PA), polyvinyl alcohol (PVA), or polymer. Vinyl cinnamate (PVCi), polymethyl methacrylate (PMMA), other suitable photoresist materials, or combinations thereof. The inorganic insulating material may be silicon oxide, silicon nitride, silicon oxynitride, siloxane, or other suitable insulating materials. However, the present invention is not limited to the above materials. For example, in one embodiment, the protective layer 14 may be a transparent material. In other embodiments, the protective layer 14 may also be doped with a fluorescent dye, a quantum dot material, a YAG phosphor, other suitable wavelength conversion materials, or a combination thereof in a transparent material.
另外，顯示面板1可更包括一遮光層15。如第1圖所示，遮光層15係位於保護層14的數個圖案化保護單元14U之間形成的間隙中。當顏色轉換層13為多孔材料的情況下，遮光層15更填充於顏色轉換層13的孔隙中，以形成在黑色矩陣層11上。換句話說，黑色矩陣層11位於基板10與遮光層15之間。 In addition, the display panel 1 may further include a light shielding layer 15. As shown in FIG. 1, the light shielding layer 15 is located in a gap formed between the plurality of patterned protection units 14U of the protection layer 14. When the color conversion layer 13 is a porous material, the light shielding layer 15 is further filled in the pores of the color conversion layer 13 to be formed on the black matrix layer 11. In other words, the black matrix layer 11 is located between the substrate 10 and the light shielding layer 15.
遮光層15可用以避免來自顯示面板1另一側基板(未繪示，在此例如是陣列基板)的入射光在相鄰之畫素單元P1、P2、P3之間產生混色。在一實施例中，遮光層15可例如是黑色光阻，但不以此為限。在另一實施例中，遮光層15也可例如是具有反射光線能力的材料，以進一步提升出光效率。在一實施例中，遮光層15於基板10的法線方向(例如沿Z軸延伸的方向)上係延伸超過保護層14，但此非用以限制本發明。 The light shielding layer 15 can be used to prevent the incident light from the substrate (not shown, such as an array substrate) on the other side of the display panel 1 from generating color mixture between adjacent pixel units P1, P2, and P3. In one embodiment, the light shielding layer 15 may be a black photoresist, but is not limited thereto. In another embodiment, the light-shielding layer 15 may also be, for example, a material capable of reflecting light, so as to further improve light output efficiency. In one embodiment, the light shielding layer 15 extends beyond the protective layer 14 in a normal direction of the substrate 10 (for example, a direction extending along the Z axis), but this is not intended to limit the present invention.
在一實施例中，若來自顯示面板1另一側基板的入射光為藍光，而彩色濾光單元12R、12G、12B分別為紅色濾光單元、綠色濾光單元及藍色濾光單元時，入射光先分別經過保護層14的圖案化保護單元14U，再經由顏色轉換層13轉換成白光後，分別從畫素單元P1、P2及P3穿過基板10出光之光線可分別呈現紅光、綠光及藍光。但此非用以限制本發明，上述入射光之顏色、顏色轉換層13、保護層14、彩色濾光單元12R、12G、12B所能轉換及/或過濾的光的顏色及/或配置數量當可隨著實際應用需求而調整。 In an embodiment, if the incident light from the substrate on the other side of the display panel 1 is blue light, and the color filter units 12R, 12G, and 12B are a red filter unit, a green filter unit, and a blue filter unit, respectively, The incident light passes through the patterned protection unit 14U of the protection layer 14 respectively, and then is converted into white light by the color conversion layer 13. The light emitted from the pixel units P1, P2, and P3 through the substrate 10 can be red, green Light and blue light. However, this is not intended to limit the present invention. The color of the incident light, the color conversion layer 13, the protective layer 14, and the color filter units 12R, 12G, and 12B can convert and / or filter the color and / or configuration quantity of the light. It can be adjusted according to the actual application requirements.
第2A~2H圖繪示根據本發明一實施例之顯示面板1之一基板10之一側的製造實施例。 FIGS. 2A to 2H illustrate manufacturing embodiments of one side of a substrate 10 of a display panel 1 according to an embodiment of the present invention.
請參照第2A圖，首先，提供一基板10。在本實施例中，更形成一黑色矩陣層11及一彩色濾光層12於基板10上。 Referring to FIG. 2A, first, a substrate 10 is provided. In this embodiment, a black matrix layer 11 and a color filter layer 12 are further formed on the substrate 10.
接著，如第2B圖所示，形成一顏色轉換層13於基板10上。進一步地說，顏色轉換層13形成在黑色矩陣層11和彩色濾 光層12上。在此步驟中，顏色轉換層13例如是透過旋轉塗佈技術(spin coating)、噴塗塗佈技術(spray coating)而塗佈於黑色矩陣層11和彩色濾光層12上。在本實施例中，顏色轉換層13為多孔材料，例如是螢光體材料、螢光染料、量子點材料、其它合適的波長轉換材料或其組合。 Next, as shown in FIG. 2B, a color conversion layer 13 is formed on the substrate 10. Further, the color conversion layer 13 is formed on the black matrix layer 11 and the color filter On the light layer 12. In this step, the color conversion layer 13 is applied on the black matrix layer 11 and the color filter layer 12 by, for example, spin coating technology and spray coating technology. In this embodiment, the color conversion layer 13 is a porous material, such as a phosphor material, a fluorescent dye, a quantum dot material, other suitable wavelength conversion materials, or a combination thereof.
而後，可選擇性地對顏色轉換層13進行一拋光程序，得到如第2C圖所示的顏色轉換層13。 Then, a polishing process may be selectively performed on the color conversion layer 13 to obtain the color conversion layer 13 as shown in FIG. 2C.
之後，如第2D圖所示，形成一保護材料層14’，以覆蓋顏色轉換層13。在本實施例中，由於顏色轉換層13為多孔材料，故保護材料層14’可更填充於顏色轉換層13的孔隙中。 Thereafter, as shown in FIG. 2D, a protective material layer 14 'is formed to cover the color conversion layer 13. In this embodiment, since the color conversion layer 13 is a porous material, the protective material layer 14 'can be further filled in the pores of the color conversion layer 13.
接著，請參照第2E圖及第2F圖。在此，可藉由一第一光罩17進行曝光顯影製程，將整層的保護材料層14’圖案化去除未被曝光的部分，並使之硬化而製作成如第2F圖所示的保護層14。此時，保護層14可包括數個圖案化保護單元14U，且相鄰的圖案化保護單元14U之間分別具有一間隙141。 Next, please refer to FIG. 2E and FIG. 2F. Here, a first photomask 17 may be used for the exposure and development process to pattern the entire protective material layer 14 ′ to remove the unexposed portions, and harden them to form a protection as shown in FIG. 2F Layer 14. At this time, the protection layer 14 may include a plurality of patterned protection units 14U, and a gap 141 is formed between adjacent patterned protection units 14U.
在本實施例中，顏色轉換層13在上述過程中並不易被顯影移除。因此，在經過第2F圖的顯影製程後，仍有部分的顏色轉換層13的材料殘留於間隙141中。 In this embodiment, the color conversion layer 13 is not easily removed by development during the above process. Therefore, after the development process of FIG. 2F, a part of the material of the color conversion layer 13 remains in the gap 141.
接著，請參照第2G圖，形成一遮光材料層15’於基板10、顏色轉換層13及保護層14上。進一步地說，遮光材料層15’除了形成在保護層14上，還形成在圖案化保護單元14U之間所形 成的間隙141中，且更填充於位在間隙141中的顏色轉換層13的孔隙中，以形成在黑色矩陣層11上。 Next, referring to FIG. 2G, a light-shielding material layer 15 'is formed on the substrate 10, the color conversion layer 13, and the protective layer 14. Further, in addition to the light-shielding material layer 15 'being formed on the protection layer 14, it is also formed between the patterned protection units 14U. The gaps 141 formed are filled in the pores of the color conversion layer 13 located in the gaps 141 to form the black matrix layer 11.
接著，請參照第2H圖及第1圖。在此，可藉由一第二光罩18進行曝光顯影製程，將整層的遮光材料層15’圖案化去除未被曝光的部分，並使之硬化而製作成如第1圖所示的遮光層15。此時，遮光層15位於保護層14的數個圖案化保護單元14U之間形成的間隙141(標示於第2F圖及第2G圖)中。 Next, please refer to FIG. 2H and FIG. 1. Here, a second photomask 18 may be used for the exposure and development process to pattern the entire light-shielding material layer 15 ′ to remove unexposed parts, and then harden them to produce light-shielding as shown in FIG. 1. Layer 15. At this time, the light shielding layer 15 is located in a gap 141 (labeled in FIG. 2F and FIG. 2G) formed between the plurality of patterned protection units 14U of the protection layer 14.
在第2A~2H圖中，由於在各畫素單元P1、P2、P3中均有保護層14的圖案化保護單元14U覆蓋顏色轉換層13，圖案化保護單元14U在遮光材料層15’的顯影過程中起到保護顏色轉換層13的作用，避免顏色轉換層13於顯影的過程中受到損傷而產生缺陷。 In FIGS. 2A to 2H, since each pixel unit P1, P2, P3 has a patterned protection unit 14U with a protective layer 14 covering the color conversion layer 13, the patterned protection unit 14U is developed on the light-shielding material layer 15 '. In the process, it protects the color conversion layer 13 and prevents the color conversion layer 13 from being damaged during the development process and causing defects.
此外，若在圖案化保護單元14U之間所形成的間隙141中同時含有顏色轉換層13及遮光層15的結構，可使光線產生互補效果，進而提升此區域的遮光能力。 In addition, if the gap 141 formed between the patterned protection units 14U includes both the color conversion layer 13 and the light-shielding layer 15 structure, the light can have a complementary effect, thereby improving the light-shielding ability in this area.
請參照第3圖，其繪示根據本發明第二實施例之顯示面板2之一基板10之一側的剖視圖。在本實施例中，顯示面板2包括一顏色轉換層23。此顏色轉換層23在進行顯影保護材料層14’的過程中(如第2F圖所示)，係容易被顯影移除的材料。因此，在經過第2F圖的顯影製程後，幾乎沒有顏色轉換層23的材料殘留於間隙141中。 Please refer to FIG. 3, which illustrates a cross-sectional view of one side of a substrate 10 of a display panel 2 according to a second embodiment of the present invention. In this embodiment, the display panel 2 includes a color conversion layer 23. This color conversion layer 23 is a material that is easily removed by development during the development of the protective material layer 14 '(as shown in FIG. 2F). Therefore, after the development process of FIG. 2F, almost no material of the color conversion layer 23 remains in the gap 141.
請參照第4圖，其繪示根據本發明第三實施例之顯示面板3之一基板10之一側的剖視圖。在本實施例中，顯示面板3包括一顏色轉換層33。顏色轉換層33與上述實施例之顏色轉換層13、23不同之一處在於：顏色轉換層33可為無孔洞的材料。因此，保護層14的各圖案化保護單元14U係位於顏色轉換層33上。 Please refer to FIG. 4, which is a cross-sectional view of one side of a substrate 10 of a display panel 3 according to a third embodiment of the present invention. In this embodiment, the display panel 3 includes a color conversion layer 33. One of the differences between the color conversion layer 33 and the color conversion layers 13 and 23 in the above embodiment is that the color conversion layer 33 can be a non-hole material. Therefore, each of the patterned protection units 14U of the protection layer 14 is located on the color conversion layer 33.
在第4圖的實施例中，於進行顯影保護材料層14’的過程中(如第2F圖所示)，可一併移除未被圖案化保護單元14U覆蓋的一部分顏色轉換層33。接著，再繼續進行如第2G圖形成一遮光材料層15’之後的步驟。 In the embodiment of FIG. 4, during the process of developing the protective material layer 14 ′ (as shown in FIG. 2F), a part of the color conversion layer 33 not covered by the patterned protection unit 14U can be removed together. Then, the steps after forming a light-shielding material layer 15 'as shown in FIG. 2G are continued.
請參照第5圖，其繪示根據本發明第四實施例之顯示面板4之一基板10之一側的剖視圖。在本實施例中，顯示面板4包括一彩色濾光層42。彩色濾光層42與上述實施例之彩色濾光層12不同之一處在於：彩色濾光層42包括厚度不同的彩色濾光單元42R、42G、42B。詳細地說，在如第2A圖形成彩色濾光層42的步驟中，所形成的彩色濾光單元42B具有大於彩色濾光單元42R、42G的厚度，以進一步增加藍光的出光效果。接著，再基於這樣的彩色濾光層42的結構，繼續進行後續第2B圖至第2H圖之步驟，且不再於畫素單元P3處形成保護層14。 Please refer to FIG. 5, which illustrates a cross-sectional view of one side of a substrate 10 of a display panel 4 according to a fourth embodiment of the present invention. In this embodiment, the display panel 4 includes a color filter layer 42. One difference between the color filter layer 42 and the color filter layer 12 of the above embodiment is that the color filter layer 42 includes color filter units 42R, 42G, and 42B with different thicknesses. In detail, in the step of forming the color filter layer 42 as shown in FIG. 2A, the formed color filter unit 42B has a thickness greater than that of the color filter units 42R and 42G, so as to further increase the light-emitting effect of blue light. Then, based on the structure of the color filter layer 42, the subsequent steps from FIG. 2B to FIG. 2H are continued, and the protective layer 14 is no longer formed at the pixel unit P3.
或者，在另一實施例中，在如第2A圖形成彩色濾光層12的步驟後，可先在畫素單元P3處形成一初始保護層於彩色濾光單元12B上。接著，再基於這樣的結構，繼續進行後續第2B圖至第2H圖之步驟，且不再於畫素單元P3處形成保護層14。 Alternatively, in another embodiment, after the step of forming the color filter layer 12 as shown in FIG. 2A, an initial protective layer may be formed on the pixel unit P3 on the color filter unit 12B. Then, based on such a structure, the subsequent steps from FIG. 2B to FIG. 2H are continued, and the protective layer 14 is no longer formed at the pixel unit P3.
請參照第6圖，其繪示根據本發明第五實施例之顯示面板5之一基板10之一側的剖視圖。在本實施例中，可在形成遮光層15的步驟後，再選擇性地對遮光層15進行一拋光程序，以去除在基板10的法線方向(例如沿Z軸延伸的方向)上延伸超過保護層14的部分遮光層15。 Please refer to FIG. 6, which illustrates a cross-sectional view of one side of a substrate 10 of a display panel 5 according to a fifth embodiment of the present invention. In this embodiment, after the step of forming the light-shielding layer 15, a polishing process may be selectively performed on the light-shielding layer 15 to remove the light-shielding layer 15 from extending beyond a normal direction of the substrate 10 (for example, a direction extending along the Z axis). Part of the protective layer 14 is a light-shielding layer 15.
此外，在另一實施例中，亦可對第6圖所示之結構再重複進行上述第2B圖至第2H圖之步驟，以形成另一顏色轉換層13、保護層14及遮光層15堆疊的結構。 In addition, in another embodiment, the steps shown in FIG. 2B to FIG. 2H can be repeated for the structure shown in FIG. 6 to form another color conversion layer 13, a protection layer 14, and a light-shielding layer 15. Structure.
請參照第7圖，其繪示根據本發明第六實施例之顯示面板6之一基板60之一側的剖視圖。本實施例與上述任一實施例不同之一處在於：基板60可以是陣列基板。本實施例中，基板60為遠離觀看者(例如：人眼)之一側。舉例來說，圖面所示之Z軸正方向的視角，可為觀看者觀看顯示面板6時之視角。 Please refer to FIG. 7, which is a cross-sectional view of one side of a substrate 60 of a display panel 6 according to a sixth embodiment of the present invention. This embodiment is different from any of the above embodiments in that the substrate 60 may be an array substrate. In this embodiment, the substrate 60 is away from one side of the viewer (for example, human eyes). For example, the viewing angle in the positive direction of the Z axis shown in the figure may be the viewing angle when the viewer views the display panel 6.
顯示面板6可包括一發光層66，例如是一自發光層。發光層66可設置於基板60的內表面。發光層66可包括數個發光單元66L，每一個發光單元66L各對應於一個畫素單元P1、P2、P3，例如可一對一地對應於畫素單元P1、P2、P3。在一實施例中，每一個發光單元66L可包括單層或多層結構/材料，例如是有機發光二極體、微型發光二極體、量子點材料、鈣鈦礦材料、其它合適的發光材料或前述之組成。 The display panel 6 may include a light-emitting layer 66, such as a self-emitting layer. The light emitting layer 66 may be disposed on an inner surface of the substrate 60. The light-emitting layer 66 may include a plurality of light-emitting units 66L, and each of the light-emitting units 66L corresponds to one pixel unit P1, P2, P3, for example, may correspond to the pixel units P1, P2, P3 one-to-one. In one embodiment, each light-emitting unit 66L may include a single-layer or multi-layer structure / material, such as an organic light-emitting diode, a micro-light-emitting diode, a quantum dot material, a perovskite material, other suitable light-emitting materials, or The aforementioned composition.
顏色轉換層13可形成於基板60及發光層66上，換言之，發光層66係位於基板60與顏色轉換層13之間。在本實施例中，顏色轉換層13可以是多孔材料，但並不以此為限。 The color conversion layer 13 may be formed on the substrate 60 and the light emitting layer 66. In other words, the light emitting layer 66 is located between the substrate 60 and the color conversion layer 13. In this embodiment, the color conversion layer 13 may be a porous material, but is not limited thereto.
保護層14覆蓋顏色轉換層13，且保護層14的圖案化保護單元14U更填充於顏色轉換層13的孔隙中。 The protective layer 14 covers the color conversion layer 13, and the patterned protection unit 14U of the protective layer 14 is further filled in the pores of the color conversion layer 13.
此外，遮光層15位於保護層14的數個圖案化保護單元14U之間形成的間隙中。更進一步地說，遮光層15更填充於顏色轉換層13的孔隙中，以形成在基板60的內表面上。在本實施例中，遮光層15於基板60的法線方向(例如沿Z軸延伸的方向)上係延伸超過保護層14，但並不以此為限。 In addition, the light shielding layer 15 is located in a gap formed between the plurality of patterned protection units 14U of the protection layer 14. Furthermore, the light shielding layer 15 is filled in the pores of the color conversion layer 13 to be formed on the inner surface of the substrate 60. In this embodiment, the light shielding layer 15 extends beyond the protective layer 14 in a normal direction of the substrate 60 (for example, a direction extending along the Z axis), but is not limited thereto.
顯示面板6可更包括一彩色濾光層62。彩色濾光層62包括數個彩色濾光單元62R、62G、62B。每一個彩色濾光單元62R、62G、62B各位於一個圖案化保護單元14U上。此外，這些彩色濾光單元62R、62G、62B可由遮光層15所隔開，以避免來自發光單元66L的入射光在相鄰之畫素單元P1、P2、P3之間產生混色。 The display panel 6 may further include a color filter layer 62. The color filter layer 62 includes a plurality of color filter units 62R, 62G, and 62B. Each of the color filter units 62R, 62G, and 62B is located on a patterned protection unit 14U. In addition, the color filter units 62R, 62G, and 62B can be separated by the light-shielding layer 15 to prevent the incident light from the light-emitting unit 66L from mixing colors between adjacent pixel units P1, P2, and P3.
