Through setting up the arch at the surface towards sealing the frame glue of bed hedgehopping layer, can increase the area of contact between bed hedgehopping layer and the frame glue, and then promote the reliability of display substrate.
In one embodiment, as shown in fig. 2 and 3, in order to prevent the edge area of the array substrate from tilting after the array substrate and the color film substrate are aligned, the thickness of each film layer satisfies the following relationship:
H 22 +H 40 ＝H 1 +H 16 +H 18 +H 19 +H 23 +H 26 －H 25 +△H 24
wherein H is 22 Is the thickness of the lift-off layer 22; h 40 The thickness of the frame sealing glue 40; h 1 The distance between the array substrate and the color film substrate in the display area is the same as the distance between the array substrate and the color film substrate in the display area; h 16 Is the thickness of the first electrode 16; h 18 Is the thickness of the second electrode 18; h 19 Is the thickness of the liquid crystal alignment film layer 19; h 23 Is the thickness of the liquid crystal alignment layer 23; h 26 Is the thickness of the color film layer 26; h 25 Is the thickness of the light shielding layer 25; deltaH 24 Is a thickness difference between a portion of the organic resin layer 24 located in the display region and a portion located in the first sub-frame region.
In one embodiment, as shown in fig. 4, the light shielding layer 25 includes a light shielding portion 251 located in the first sub-frame region 103, and the thickness of the light shielding portion 251 is greater than that of other regions of the light shielding layer 25; the raised layer 22 is the light shielding portion 251. In this way, the raised layer 22 and the light shielding layer 25 are formed simultaneously, and the formation of the raised layer 22 does not require additional preparation steps, which is helpful for simplifying the complexity of the preparation process of the display substrate. The light shielding layer 25 may be prepared using a gray-scale mask, and the light transmittance of the region corresponding to the light shielding part 251 of the gray-scale mask is different from that of the other regions of the gray-scale mask.
In one embodiment, as shown in fig. 5, the backing layer 22 is disposed on the same layer as the color film layer 26. Thus, the raised layer 22 and the color film layer 26 are formed simultaneously, and the formation of the raised layer 22 does not require additional process steps, which is helpful for simplifying the manufacturing process complexity of the display substrate. In this embodiment, the lift-off layer 22 is located on the side of the light-shielding layer 25 facing away from the substrate 21.
In one embodiment, the edge of the orthographic projection of the sealant 40 on the substrate 21 is located inside the edge of the orthographic projection of the lift-off layer 22 on the substrate 21. By the arrangement, the situation that the frame sealing glue 40 is contacted with the liquid crystal alignment layer due to the fact that the width of the pad high layer 22 is smaller in the process of preparing the pad high layer 22 caused by process errors can be effectively avoided.
Further, the ratio of the distance from the edge of the front projection of the frame sealing glue 40 on the substrate 21 to the edge of the same side of the front projection of the pad layer 22 on the substrate 21 to the width of the frame sealing glue 40 is in the range of 1/5-1/3. By the arrangement, the frame sealing glue 40 is effectively prevented from contacting the liquid crystal alignment layer, and the width of the first sub-frame area 103 is not increased too much. In some embodiments, the ratio may be 1/5, 1/4, 1/3, etc.
In one embodiment, the coating error in the process of coating the frame sealing glue 40 is 100 μm, the etching error in preparing the raised layer 22 is 2 μm, and the distance from two edges of the front projection of the frame sealing glue 40 on the substrate 21 to the edge on the same side of the front projection of the raised layer 22 on the substrate 21 is greater than or equal to 102 μm. For example, when the width of the seal 40 is 800 μm, the width of the spacer layer 22 is 1004 μm or more. By this arrangement, even if the coating error and the etching error reach the maximum, the orthographic projection of the frame sealing glue 40 on the substrate 21 can be completely within the orthographic projection of the pad layer 22 on the substrate 21.
In one embodiment, the material of the light shielding layer 25 is metal, and the spacer layer 22 is in direct contact with the frame sealing glue 40. By arranging the light shielding layer 25 of metal, the material of the light shielding layer 25 is prevented from remaining in the through hole when the through hole is formed on the light shielding layer 25, so that the formation of a pixel dark spot is avoided; the higher reflectivity of the spacer layer 22 can improve the problem that the width of the frame sealing glue cannot be detected due to the reflection of the light shielding layer when the width of the frame sealing glue is detected by an optical instrument after the frame sealing glue 40 is formed.
Further, the color film substrate further includes an auxiliary film layer located at a side of the light shielding layer 25 away from the substrate 21, the auxiliary film layer is located in the first sub-frame area 103, and the orthographic projection of the frame sealing glue 40 on the substrate 21 falls within the orthographic projection of the auxiliary film layer on the substrate 21; the reflectivity of the auxiliary film layer is smaller than that of the light shielding layer 25. By forming the auxiliary film layer on the side of the light shielding layer 25 away from the substrate, and the reflectivity of the auxiliary film layer is lower than that of the light shielding layer, the problem that the width of the frame sealing adhesive cannot be detected due to reflection of the light shielding layer can be further improved. In this embodiment, the display substrate may be used for a virtual reality display device, which may meet the high requirements of the virtual reality display device for visual effects.
Further, the color film layer comprises a blue light filtering structure; the auxiliary film layer and the blue light filtering structure are arranged on the same layer. The auxiliary film layer and the blue light filtering structure in the color film layer can be formed simultaneously, so that the complexity of the preparation process of the display substrate is simplified; and the reflectivity of the blue filtering structure is smaller than that of the filtering structures with other colors, which is more beneficial to improving the problem that the width of the frame sealing glue cannot be detected due to the reflection of the shading layer.
For the embodiment shown in fig. 2, it was found by experiments that when the thickness of the lift-off layer 22 is greater than or equal to 0.8 μm, the thickness uniformity of the lift-off layer 22 is good; the minimum wet area of the frame sealing adhesive is more than or equal to 1000 mu m 2 The method comprises the steps of carrying out a first treatment on the surface of the The smallest dimension of the silicon balls 41 in the current frame sealing glue 40 is 1.7 μm. The sum of the thicknesses of the lift-up layer 22 and the frame sealing adhesive 40 is generally 4.5 μm when the display device is a vehicle-mounted display device; the sum of the thicknesses of the lift-off layer 22 and the frame sealing glue 40 is typically 3.3 μm when the display device is used in a virtual reality device.
As can be determined from the above values, the size of the silicon ball 41 is 3.7 μm when the thickness of the lift-up layer 22 is 0.8 μm and the display device is a vehicle-mounted display device; the size of the silicon sphere 41 when the display device is used in a virtual reality device is 2.5 μm. Both values are greater than 1.7 μm. When the wet area of the frame sealing glue is minimum, the width of the frame sealing glue is 1000 mu m when the display device is a vehicle-mounted display device 2 3.7 μm=270 μm, i.e. the width of the frame sealing glue of the vehicle-mounted display device is larger than 270 μm; the width of the frame sealing adhesive of the vehicle-mounted display device is generally larger than or equal to 1000 μm. When the wet area of the frame sealing glue is minimum, the width of the frame sealing glue is 1000 mu m when the display equipment is virtual reality equipment 2 2.5 μm=400 μm, i.e. the width of the frame sealing glue of the virtual reality device is larger than 400 μm; the width of the frame sealing glue of the virtual reality device is generally about 600 μm.
