Description

顯示面板Display panel

本發明是有關於一種顯示面板，且特別是有關於一種彩色濾光層位於畫素陣列層上的顯示面板。The present invention relates to a display panel, and more particularly to a display panel in which a color filter layer is disposed on a pixel array layer.

隨著科技的進步，顯示器的技術也不斷地發展。輕、薄、短、小的平面顯示器(Flat Panel Display, FPD)逐漸取代傳統厚重的陰極映像管顯示器(Cathode Ray Tube, CRT)。如今，由於平面顯示器的輕薄特性，平面顯示器更被配置到許多建築物或電子設備的非平面的表面上。With the advancement of technology, the technology of display has also been continuously developed. Light, thin, short, and small flat panel displays (FPD) are gradually replacing traditional heavy cathode ray tube displays (CRTs). Today, flat panel displays are more configurable on non-planar surfaces of many buildings or electronic devices due to the thin and light nature of flat panel displays.

為了要配合非平面的表面，顯示面板亦要跟著具有些許弧度，故彎曲顯示面板亦被提出。在習知的液晶顯示面板中，通常具有間隙物，用以維持顯示面板的上基板以及下基板之間的間隙(cell gap)。然而，在製作曲面(curved)顯示面板的過程中，若上下基板遇到錯位的問題，則會造成間隙物撞擊***(Tsuno)，進而導致液晶層產生氣泡。一般來說，在彩色濾光層位於畫素陣列層上(Color Filter on Array, COA)的液晶顯示面板中，彼此交疊的彩色濾光圖案會造成前述***，因此導致顯示面板的良率下降。In order to match the non-planar surface, the display panel also has a slight curvature, so a curved display panel is also proposed. In a conventional liquid crystal display panel, there is usually a spacer for maintaining a cell gap between the upper substrate and the lower substrate of the display panel. However, in the process of manufacturing a curved display panel, if the upper and lower substrates encounter a problem of misalignment, the spacers may cause a collision (Tsuno), which may cause bubbles in the liquid crystal layer. Generally, in a liquid crystal display panel in which a color filter layer is disposed on a color filter on Array (COA), color filter patterns overlapping each other cause the above-mentioned ridge, thereby causing a decrease in yield of the display panel. .

本發明提供一種顯示面板，可避免間隙物撞擊***，以改善液晶層產生氣泡的問題。The invention provides a display panel which can prevent the spacer from colliding with the ridge to improve the problem of bubble generation in the liquid crystal layer.

本發明提出一種顯示面板。顯示面板包括第一基板、畫素陣列層、彩色濾光層、第二基板以及間隙物。畫素陣列層位於第一基板上，包括多個畫素列，各畫素列包括第一畫素單元、第二畫素單元以及第三畫素單元。彩色濾光層位於畫素陣列層上。彩色濾光層包括第一彩色濾光圖案、第二彩色濾光圖案以及第三彩色濾光圖案。第一彩色濾光圖案位於第一畫素單元上方與兩相鄰畫素列之間的區域上方。第二彩色濾光圖案位於第二畫素單元上方。第三彩色濾光圖案位於第三畫素單元上方。第二基板與第一基板對向配置。間隙物配置於兩相鄰畫素列之間的區域上方的部分第一彩色濾光圖案與第二基板之間。The invention provides a display panel. The display panel includes a first substrate, a pixel array layer, a color filter layer, a second substrate, and a spacer. The pixel array layer is located on the first substrate and includes a plurality of pixel columns, and each pixel column includes a first pixel unit, a second pixel unit, and a third pixel unit. The color filter layer is on the pixel array layer. The color filter layer includes a first color filter pattern, a second color filter pattern, and a third color filter pattern. The first color filter pattern is located above the area between the first pixel unit and the two adjacent pixel columns. The second color filter pattern is located above the second pixel unit. The third color filter pattern is located above the third pixel unit. The second substrate is disposed opposite to the first substrate. The spacer is disposed between the portion of the first color filter pattern and the second substrate above the region between the two adjacent pixel columns.

基於上述，本發明的第一彩色濾光圖案具有位於第一畫素單元上方與兩相鄰畫素列之間的區域上方的特殊形狀，使得對應於兩相鄰畫素列之間的區域的第一彩色濾光圖案不會與其他彩色濾光圖案重疊，因而避免該處具有***形成。如此一來，當上下基板發生錯位的情形時，能避免間隙物撞擊到因濾光圖案堆疊所致的***，進而改善液晶層產生氣泡的問題。因此，顯示面板具有較佳的良率與顯示品質。Based on the above, the first color filter pattern of the present invention has a special shape above the area between the first pixel unit and the two adjacent pixel columns such that it corresponds to the area between the two adjacent pixel columns. The first color filter pattern does not overlap with other color filter patterns, thereby avoiding the formation of ridges there. In this way, when the upper and lower substrates are misaligned, it is possible to prevent the spacer from colliding with the ridge due to the stacking of the filter patterns, thereby improving the problem of bubble generation in the liquid crystal layer. Therefore, the display panel has better yield and display quality.

In general, when the first and second substrates 102, 104 are misaligned, the spacers PS are generally in the region between the two adjacent pixel columns 112a, 112b (ie, on the first color filter pattern 122a). The movement in the extending direction Dc, but in order to avoid the displacement of the spacer PS in the extending direction Dc, may hit the first and second color filter patterns 122a, 122b or the first and third color filter patterns 122a. a first ridge W1 of the first color filter pattern 122a in the first direction D1 is designed to be larger than the second width of the spacer PS in the first direction D1. W2, in this way, when the spacer PS is displaced in the extending direction Dc, since the second width W2 of the spacer PS is smaller than the first width W1 of the first color filter pattern 122a, the spacer PS can be prevented from colliding The bulging of the junction further improves the problem of the display medium layer 140 generating bubbles. In other words, in the present embodiment, the ratio between the first width W1 and the second width W2 is, for example, 1.1 to 3.3. In the present embodiment, the first direction D1 is, for example, perpendicular to the extending direction Dc, but the invention is not limited thereto.

The directions are, for example, overlapping. That is, the light shielding pattern layer 130 shields part of the first color filter pattern 122a. In this embodiment, in the first direction D1, the first color filter pattern 122a above the region between the two adjacent pixel columns 112a, 112b has, for example, a first width W1 located in two adjacent pixel columns. The light shielding pattern layer 130 between 112a, 112b has, for example, a third width W3, and the first width W1 is, for example, smaller than the third width W3. In the present embodiment, the first width W1 and the third width W3 have, for example, the following relationship: (W1-W3)/2≧6 um. In the present embodiment, in the first direction D1, the edge of the light-shielding pattern layer 130 above the area between the two adjacent pixel columns 112a, 112b and the area between the two adjacent pixel columns 112a, 112b There is a distance d between the edges of the upper first color filter pattern 122a. In this way, it can be ensured that the light shielding pattern layer 130 shields the first color filter pattern 122a located above the area between the two adjacent pixel columns 112a, 112b. In the present embodiment, the first direction D1 is, for example, substantially perpendicular to the extending direction Dc of each of the pixel columns 112a and 112b.

在本實施例中，第一基板102與第二基板104之間例如是更配置有顯示介質層140。顯示介質層140例如是液晶材料。換言之，本實施例的顯示面板100例如是液晶顯示面板，且顯示面板100例如是用於曲面電視的液晶顯示面板。然而，本發明並不限於此。在其他實施例中，顯示介質層140亦可以是其他的顯示材料，諸如有機發光二極體材料、無機發光二極體材料、電泳顯示材料、螢光材料、磷光材料、電漿材料等。In the present embodiment, the display medium layer 140 is disposed between the first substrate 102 and the second substrate 104, for example. The display medium layer 140 is, for example, a liquid crystal material. In other words, the display panel 100 of the present embodiment is, for example, a liquid crystal display panel, and the display panel 100 is, for example, a liquid crystal display panel for a curved television. However, the invention is not limited thereto. In other embodiments, the display dielectric layer 140 may also be other display materials such as an organic light emitting diode material, an inorganic light emitting diode material, an electrophoretic display material, a fluorescent material, a phosphorescent material, a plasma material, and the like.

一般來說，在製作曲面液晶顯示面板的過程中，若上下基板遇到錯位的問題，則會造成間隙物撞擊***，進而導致液晶層產生氣泡。在本實施例中，第一彩色濾光圖案122a具有位於第一畫素單元114a上方與兩相鄰畫素列112a、112b之間的區域上方的特殊形狀，使得對應於兩相鄰畫素列112a、112b之間的區域的第一彩色濾光圖案122a不會與其他彩色濾光圖案122b、122c重疊，因而避免該處具有***形成。如此一來，當第一與第二基板102、104發生錯位的情形時，能避免移動於兩相鄰畫素列112a、112b之間的區域中的間隙物PS撞擊到***，進而改善顯示介質層140產生氣泡的問題。再者，在本實施例中，進一步將兩相鄰畫素列112a、112b之間的區域的第一彩色濾光圖案122a的寬度設計成大於或等於間隙物PS的寬度，如此可以避免間隙物PS撞擊到第一與第二彩色濾光圖案122a、122b或第一與第三彩色濾光圖案122a、122c的交界處的***Ts。此外，在本實施例中，將位於兩相鄰畫素列112a、112b之間的區域上方的遮光圖案層130的寬度設計成大於位於兩相鄰畫素列112a、112b之間的區域上方的第一彩色濾光圖案122a的寬度，且兩者邊緣之間具有距離，如此可以避免漏光現象發生。因此，顯示面板100具有較佳的良率與顯示品質。In general, in the process of fabricating a curved liquid crystal display panel, if the upper and lower substrates encounter a problem of misalignment, the spacers may be bumped and bulged, thereby causing bubbles in the liquid crystal layer. In this embodiment, the first color filter pattern 122a has a special shape above the area between the first pixel unit 114a and the two adjacent pixel columns 112a, 112b, so that it corresponds to two adjacent pixel columns. The first color filter patterns 122a of the regions between 112a, 112b do not overlap with the other color filter patterns 122b, 122c, thereby avoiding the formation of bumps there. In this way, when the first and second substrates 102, 104 are misaligned, the spacers PS moving in the region between the adjacent pixel columns 112a, 112b can be prevented from colliding to the ridge, thereby improving the display medium. Layer 140 creates the problem of bubbles. Furthermore, in the embodiment, the width of the first color filter pattern 122a of the region between the two adjacent pixel columns 112a, 112b is further designed to be greater than or equal to the width of the spacer PS, so that the spacer can be avoided. The PS strikes the ridges Ts at the intersection of the first and second color filter patterns 122a, 122b or the first and third color filter patterns 122a, 122c. Further, in the present embodiment, the width of the light-shielding pattern layer 130 above the area between the two adjacent pixel columns 112a, 112b is designed to be larger than the area between the two adjacent pixel columns 112a, 112b. The width of the first color filter pattern 122a and the distance between the edges thereof can avoid the occurrence of light leakage. Therefore, the display panel 100 has better yield and display quality.

綜上所述，在本發明中，將第一彩色濾光圖案設計為位於第一畫素單元上方以及位於兩相鄰畫素列之間的區域上方，使得兩相鄰畫素列之間的區域不會有因兩種彩色濾光圖案交曡所造成的***。如此一來，當顯示面板被彎曲而導致上下基板發生錯位的情形時，能避免移動於兩相鄰畫素列之間的區域中的間隙物撞擊到***，進而改善顯示介質層產生氣泡的問題。再者，可以調整第一彩色濾光圖案與間隙物的寬度，以進一步避免間隙物撞擊到兩相鄰畫素列之間的區域的邊緣處的因濾光圖案堆疊所致的***。此外，可以藉由整遮光圖案層與第一彩色濾光圖案的寬度設來避免漏光現象發生。因此，顯示面板具有較佳的良率與顯示品質。In summary, in the present invention, the first color filter pattern is designed to be located above the first pixel unit and above the area between two adjacent pixel columns, such that between two adjacent pixel columns There is no bulge in the area due to the intersection of the two color filter patterns. In this way, when the display panel is bent to cause the upper and lower substrates to be misaligned, the gaps in the region between the two adjacent pixel columns can be prevented from colliding with the ridges, thereby improving the problem of bubble generation in the display medium layer. . Furthermore, the width of the first color filter pattern and the spacer may be adjusted to further prevent the spacer from striking the ridge due to the stacking of the filter patterns at the edge of the region between the two adjacent pixel columns. In addition, the light leakage phenomenon can be avoided by setting the width of the entire light shielding pattern layer and the first color filter pattern. Therefore, the display panel has better yield and display quality.
