The applicant uses two unpublished solutions to improve the light leakage of the curved screen: the first is to increase the width of the black matrix 131; the second is to add a metal layer to block the light leakage part with the metal layer. Although these two methods are effective, but it will affect the panel opening rate, the product penetration rate will decline.

The application is described in detail below with reference to the drawings and embodiments.

As shown in FIGS. 2 to 4, an embodiment of the present application discloses a display panel 110 including a first substrate 120 with an arc shape, a second substrate 130 with an arc shape, a liquid crystal layer, and a sealant. The first The substrate 120 and the second substrate 130 are arranged oppositely. The first substrate 120 includes an array switch layer, a first substrate, a pixel electrode layer, a color resist layer 140 containing at least three sub-color groups with different colors, and the color resist layer The light-shielding layer 150 between each adjacent two sub-color resists 141 in 140, the first substrate includes a display area and a non-display area for displaying a picture, an array switch layer is disposed on an inner surface of the display area in the first substrate, the color resist The layer 140 and the light shielding layer 150 are disposed on the inner surface of the array switch layer, the pixel electrode layer is disposed on the surface of the color resist layer 140 and the light shielding layer 150; the liquid crystal layer and the sealant are disposed between the first substrate 120 and the second substrate 130, The sealant seals the liquid crystal layer between the first substrate 120 and the second substrate 130; the light-shielding layer 150 includes at least two sub-light-shielding layers 150 of different colors. The light-shielding layer 150 is formed by stacking the sub-light-shielding layers 150. The same material as the color resist layer 140. In the curved panel, the curvature of the first substrate 120 and the second substrate 130 are different. If the light-shielding layer 150 and the color group layer are not on the same substrate, the area of the light-shielding layer 150 is usually large, resulting in a decrease in the aperture ratio, so the light-shielding layer 150 It is provided between the adjacent sub-color resists 141 of the color resist layer 140 to maximize the light shielding effect without increasing the aperture ratio; and the light shielding layer 150 can be processed with the same material as the color resist layer 140 The color resist layer 140 completes the processing of the light-shielding layer 150 at the same time, saving processing time; since the light-shielding layer 150 of one color can only transmit light of one color, the light-shielding layer 150 is set as a sub-light-shielding layer of two different colors 150 stacking structure can play a shading role.

Generally speaking, two sub-shading layers 150 can be stacked to achieve the effect of shading. Now the shading layer 150 formed by stacking three sub-shading layers 150 is equivalent to adding a layer of filtering effect, so that the light is more difficult to transmit. The light-shielding layer 150 formed by stacking three seed light-shielding layers 150 can achieve the best light-shielding effect, because the best light-shielding effect has been achieved, and even if the number of sub-light-shielding layers 150 is increased, it cannot bring better results.

In an embodiment, the color of the first sub-light-shielding layer 151 is red, the color of the second sub-light-shielding layer 152 is green, and the color of the third sub-light-shielding layer 153 is blue; The thickness of one sub-light blocking layer 151 and the thickness of the second sub-light blocking layer 152. The color resist layer 140 generally adopts red, green, and blue sub-color resists 141, and the three sub-light-shielding layers 150 are set to the same color as the three sub-color groups, so that the corresponding sub Light shielding layer 150; the light shielding effects of the sub-light shielding layers 150 of different colors are different, and the blue third sub-light shielding layer 153 has the best light shielding effect, so increasing its thickness brings better light shielding effect.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is at the bottom, the green second sub-light shielding layer 152 is in the middle, and the blue third sub-light shielding layer 153 is above. In general, the manufacturing process of the color resist layer 140 in the display panel 110 is in the order of red, green, and blue. The process sequence of layer 140 remains the same, so that there is no conflict when processing at the same time.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is above, the green second sub-light shielding layer 152 is in the middle, and the blue third sub-light shielding layer 153 is at the bottom.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is on the top, the green second sub-light shielding layer 152 is on the bottom, and the blue third sub-light shielding layer 153 is in the middle.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is at the bottom, the green second sub-light shielding layer 152 is at the top, and the blue third sub-light shielding layer 153 is in the middle.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is in the middle, the green second sub-light shielding layer 152 is above, and the blue third sub-light shielding layer 153 is at the bottom.

In one embodiment, in the light shielding layer 150, the red first sub-light shielding layer 151 is in the middle, the green second sub-light shielding layer 152 is at the bottom, and the blue third sub-light shielding layer 153 is above.

In an embodiment, the color resists of the three colors in the light shielding layer 150 are stacked randomly, and each sub-light shielding layer includes color resists of multiple colors, and the color resists of multiple colors are staggered.

In one embodiment, the color resist layer 140 includes four sub-color resist layers with different colors of red, green, blue, and white, and the light-shielding layer 150 includes at least two colors among three colors of red, green, and blue. Sub-shading layer.

The invention of the present application is also applicable to a display panel containing four kinds of color resists, and the white color resist 2145 is used to increase the brightness without increasing power consumption.

In one embodiment, the color resist layer 140 includes red, green, blue, and yellow sub-color resist layers, and the light-shielding layer 150 includes at least two of the red, green, blue, and yellow colors. Color sub-shade. The addition of yellow, red, green, and blue primary colors effectively improves the color saturation of the display panel.

In an embodiment, the second substrate 130 includes a black matrix 131, which is disposed above the light shielding layer 150 and overlapped with the light shielding layer. That is, the shading layer and the black matrix are projected onto the same vertical plane, and their projections will overlap but will not overlap. A black matrix 131 is provided above the light shielding layer 150 to prevent gaps between the light shielding layer 150 and the color layer to cause light leakage. At this time, the black matrix 131 can also play a second light shielding effect, which is more safe; because the first substrate 120 Unlike the curvature of the second substrate 130, if the black matrix 131 is provided directly above the light-shielding layer 150, the projection of the black matrix 131 will not overlap with the light-shielding layer 150, resulting in the black matrix 131 being unable to completely block the sub-color resistance 141 The light transmitted through the gap; and adjusting the position of the black matrix 131 according to the curvatures of the first substrate 120 and the second substrate 130 can enable the black matrix 131 to just reach the maximum utilization rate.

In an embodiment, as shown in FIG. 3, the second substrate 130 includes support pillars 132. The support pillars 132 are disposed on the surface of the black matrix 131 and have the same material as the black matrix 131. Due to the different curvatures of the first substrate 120 and the second substrate 130, the light transmitted between the color resist layer 140 does not perpendicularly hit the black matrix 131, but hits a slightly deviated position. The black matrix 131 and the color The greater the distance between the resistance layer 140 and the greater the deviation, the distance can be reduced by placing the support pillar 132 on the surface of the black matrix 131 to reduce the deviation. In addition, since the material of the black matrix 131 and the support pillar 132 are the same, the black matrix 131 can be completed by a process Processing with support column 132 reduces processing time and increases productivity.

In one embodiment, as shown in FIG. 4, the light-shielding layer 150 includes a fourth sub-light-shielding layer 154 and a fifth sub-light-shielding layer 155. The light-shielding layer 150 is composed of the fourth sub-light-shielding layer 154 and the fifth sub-light-shielding layer 155. Different sub-shading layers 150 are stacked. Since the color resist layer 140 needs to form three sub-color resists 141 through three masks, if the sub-light-shielding layer 150 is simultaneously formed in the photo mask process corresponding to the sub-color resist 141, a corresponding photo mask needs to be re-made. Since this technical solution has only two sub-shading layers 150, as long as the photomasks of the corresponding two sub-color resistive layers 141 and 140 are changed, the photomasks corresponding to the third sub-color resistive layer 141 does not need to be changed, saving costs .

In an embodiment, the color of the fourth sub-shielding layer 154 is red, and the color of the fifth sub-shielding layer 155 is blue; in this embodiment, the arrangement of the blue color resist and the red color resist is not required, and the blue color resist is Above, the red color resistance is on the top, or the red and blue resistances are staggered. Among the three colors of red, green and blue, the shading effect of red and blue is the best, and the shading effect of green is the worst, so the first sub-shading layer 151 and the fifth sub-shading layer 155 are set to red and blue, thus shading The light blocking effect of the layer 150 will be better.

In one embodiment, the height of the light shielding layer 150 does not exceed the height of the color resist layer 140. Since the first substrate 120 is curved, light is not always perpendicular to the first substrate 120 when it passes through the first substrate 120. When the light-shielding layer 150 protrudes and the color resist layer 140, the protruding portion may generate shadows. As a result, part of the light in the display panel 110 is relatively dark. To avoid this situation, the light shielding layer 150 is set so as not to exceed the color resist layer 140, so that no adverse effects will occur.

In one embodiment, the black photo spacer (BPS) technology is used to combine the two processes of the black matrix 131 process and the support column 132 process into a single process. The two structures are processed at the same time through one process, reducing process steps and increasing productivity.

As another embodiment of the present application, as shown in FIG. 2, a display panel 110 is disclosed, including a first substrate 120 having an arc shape and a second substrate 130 having an arc shape, the first substrate 120 and the first The two substrates 130 are oppositely arranged. The first substrate 120 includes a color resist layer 140 containing at least three sub-color groups with different colors, and a light-shielding layer 150 disposed between each adjacent two sub-color resists 141 in the color resist layer 140. The light-shielding layer 150 includes a first sub-light-shielding layer 151, a second sub-light-shielding layer 152, and a third sub-light-shielding layer 153. The light-shielding layer 150 is formed by stacking the three kinds of sub-light-shielding layers 150, wherein the color of the first sub-light-shielding layer 151 is red The color of the second sub-shielding layer 152 is green, and the color of the third sub-shielding layer 153 is blue; the three sub-shielding layers 150 are made of the same material as the color resist layer 140; the thickness of the third sub-shielding layer 153 is greater than that of the first The thickness of the sub light shielding layer 151 and the thickness of the second sub light shielding layer 152. In the curved panel, the curvature of the first substrate 120 and the second substrate 130 are different. If the light-shielding layer 150 and the color group layer are not on the same substrate, the area of the light-shielding layer 150 is usually large, resulting in a decrease in the aperture ratio, so the light-shielding layer 150 It is provided between the adjacent sub-color resists 141 of the color resist layer 140 to maximize the light shielding effect without increasing the aperture ratio; and the light shielding layer 150 can be processed with the same material as the color resist layer 140 The color resist layer 140 completes the processing of the light-shielding layer 150 at the same time, saving processing time; since the light-shielding layer 150 of one color can only transmit light of one color, the light-shielding layer 150 is set as a sub-light-shielding layer of two different colors 150 stacking structure can play a shading role.

As another embodiment of the present application, as shown in FIGS. 2 to 4, a display device 100 is disclosed, including the above-mentioned display panel 110.
