First embodiment:
referring to fig. 1 and fig. 2, in an embodiment of the present application, an array substrate 100 is provided, which includes a first substrate 110, a wiring layer 120, and a color photoresist layer 140 stacked in order. Specifically, the array substrate 100 further includes an insulating layer formed between the trace layer 120 and the color photoresist layer 140, a planarization layer 150 formed on the color photoresist layer 140, and an electrode layer 160 formed on the planarization layer 150. The PI layer is formed on the electrode layer 160 and is in contact with the spacer formed on the counter substrate. The electrode layer 160 includes a pixel electrode and a common voltage signal line. The pixel electrode and the common voltage signal line are made of a transparent conductive material ITO (Indium tin oxide).
The trace layer 120 includes scan lines 121 and common traces 122 arranged at intervals. Specifically, the wiring layer 120 further includes a data line 123 and a TFT (Thin Film Transistor ). The scan lines 121 and the data lines 123 are insulated from each other to alternately divide a plurality of pixel regions arranged in an array. The TFT is located in the pixel region, and includes a Gate (Gate) layer, a Gate Insulator (GI) layer 126, an active layer, and a Source Drain (SD) layer 125, which are sequentially disposed. The gate electrode layer has a gate electrode 124, the gate electrode 124 is connected to the scan line 121, the source electrode and the drain electrode are electrically connected to the pixel electrode, and the common wiring 122 is located on the same layer as the gate electrode 124 of the TFT and is electrically connected to the common voltage signal line.
The color photoresist layer 140 includes a filter layer 141 and a light shielding layer 142. The light shielding layers 142 are disposed above the scan lines 121 in a one-to-one correspondence manner, and are used for blocking light. Specifically, the filter layer 141 includes a red filter unit, a green filter unit, and a blue filter unit respectively corresponding to the different pixel regions. The light shielding layer 142 is generally formed by laminating two of a red filter layer, a green filter layer, and a blue filter layer, and preferably is formed by laminating a red filter layer and a green filter layer. And the light shielding layer 142 covers the opposite region of the spacer formed on the opposite substrate.
At least one side of the corresponding region of the opposite position 500 between the light shielding layer 142 and the spacer has a light shielding portion 143, and the light shielding portion 143 extends toward the filter layer 141. Specifically, the light shielding portion 143 may be integrally formed with the light shielding layer 142, or may be provided separately from the light shielding layer 142. And the light shielding portion 143 is different in color from the filter unit corresponding to its own position. In order to reduce the emission rate of light passing through the combination structure of the light shielding portion 143 and the corresponding filter unit, the light shielding portion 143 extending onto the red filter unit is generally made of a green filter material or a blue filter material; the light shielding part 143 extending to the green filter unit is made of a red filter material or a blue filter material; the light shielding portion 143 extending to the blue filter unit is made of a green filter material or a red filter material.
The common trace 122 has an extension portion 130 corresponding to the light shielding portion 143, a projection of the extension portion 130 on the first substrate 110 and a projection of the light shielding portion 143 on the first substrate 110 at least partially overlap, and an outline of an orthographic projection of the extension portion 130 on the first substrate 110 is located outside a portion of an offset range of the corresponding spacer except a boundary line. Specifically, due to the limitation of the process, the dimensions of the extension portion 130 and the light shielding portion 143 are different, and generally the dimension of the extension portion 130 is larger than the dimension of the light shielding portion 143, as shown in fig. 2 to 10. In this way, the extension portion 130 can not only effectively support the whole light shielding portion 143, but also ensure that the stress balance of the spacer 223 in the corresponding area of the light shielding portion 143, and can also shield light when the spacer scratches the PI layer, so that multiple purposes are achieved.
In the array substrate 100 provided in this embodiment, at least one side of a region of the light shielding layer 142 corresponding to the opposite position of the spacer is provided with a light shielding portion 143 extending toward the light filtering layer 141, and the light shielding portion 143 and the light filtering layer 141 are combined to form a light shielding structure, meanwhile, an extension portion 130 is additionally provided on one side of the common trace 122 facing away from the scan line 121, the extension portion 130 at least partially overlaps with the projection of the light shielding portion 143 on the extension portion 130, and the outline line of the front projection of the extension portion 130 on the first substrate 110 is located outside the offset range of the corresponding spacer except the boundary line. By adopting the structure, the stress of the spacer is equivalent to that of the original light shielding layer 142 corresponding region and the newly added light shielding portion 143 corresponding region, so that the sliding probability of the spacer to the filter layer 141 can be effectively reduced, the scratch risk of the PI layer is further reduced, in addition, the arrangement of the light shielding portion 143 and the epitaxial portion 130 can shield the light rays in the respective corresponding regions when the edges of the PI layer are scratched, the light rays are prevented from being emitted out of the array substrate 100, and the display panel using the array substrate 100 is provided. Because the outer contour line of the orthographic projection of the extension portion 130 on the first substrate 110 is located at a portion of the offset range of the corresponding spacer except for the boundary line, the common trace 122, the extension portion 130, the light shielding layer 142, the light shielding portion 143 and other structures on the array substrate 100 that can play a role in shielding light can cover most of the area of the offset range of the spacer, so that the light leakage prevention effect of the array substrate 100 provided by the embodiment is excellent, and the quality of the array substrate 100 and the display panel and the display device applying the array substrate 100 are effectively improved.
Second embodiment:
referring to fig. 3 and 4, based on the first embodiment, an outline of the front projection of the epitaxial portion 130 of the present embodiment on the first substrate is at least partially an arc 131, and the arc 131 is aligned with a boundary line 170 of the offset range of the corresponding spacer.
Thus, the extension 130 can extend to the boundary line 170 of the offset range of the spacer, and the material waste is avoided, so that the unnecessary aperture ratio is reduced.
Third embodiment:
referring to fig. 5 to 8, in addition to the first embodiment, the extension portion 130 in the present embodiment has at least one first straight line portion 132 on an outer contour line of the orthographic projection of the first substrate, and the first straight line portion 132 is tangent to a boundary line 170 of the offset range of the corresponding spacer. Thus, the array substrate 100 can be prevented from leaking light well, and the aperture ratio is prevented from being adversely affected by the excessive extension 130.
The array substrate 100 provided in this embodiment includes various implementation manners:
as shown in fig. 5, when the number of the first straight line portions 132 is one, the outer contour line of the front projection of the epitaxial portion 130 on the first substrate has a second straight line portion 133, the second straight line portion 133 is connected to the first straight line portion 132, and the inclination angle of the second straight line portion 133 is consistent with the inclination angle of the corresponding pixel electrode.
In a second implementation, as shown in fig. 7, when the number of the first straight portions 132 is two, the two first straight portions 132 are connected to each other to form an obtuse angle structure. The opening of the obtuse angle structure faces to the central area of the offset range of the spacer. And the center-to-center distances of the offset ranges of the two first straight portions 132 and the spacers are consistent.
Wherein the second implementation has a higher aperture ratio than the first implementation.
Fourth embodiment:
because the spacer includes the main spacer and the auxiliary spacer, each of the above-mentioned embodiments is only suitable for the auxiliary spacer, and the main spacer cannot completely shield light, so this embodiment provides an epitaxial portion design scheme suitable for the main spacer. Referring to fig. 9 and 10, in the third embodiment, the light shielding portions 143 are disposed on two sides of the corresponding region of the opposite top position 500 of the light shielding layer 142 and the spacer in the present embodiment, the extension portions 130 are disposed on the corresponding regions of the common trace 122 and the spacer 223 on two sides of the scan line 121, and the extension directions of the extension portions 130 on the common trace 122 on two sides of the same scan line 121 are opposite. Therefore, the aperture ratio is not sacrificed, and a good shading effect can be achieved.
In order to avoid the addition of the light shielding portion to increase the thickness of the local area of the color photoresist layer in the above embodiments, as shown in fig. 2, a step portion 144 extending toward the light shielding layer 142 is formed on a side of the light filtering layer 141 contacting the light shielding layer 142, the light shielding portion 143 is mounted on the step portion 144, and the top surface of the light shielding portion 143 is flush with the top surfaces of the light filtering layer 141 and the light shielding layer 142. Thus, the thickness of each region of the color photoresist layer 140 is ensured to be equivalent, the processing is convenient, and the aesthetic degree of the array substrate 100 is not affected.
In order to ensure good shading effect of the shading structure, and the thickness of the laminated shading part and the corresponding filtering unit is smaller, in each embodiment, the filtering layer comprises a red filtering unit, a green filtering unit and a blue filtering unit which are respectively and correspondingly positioned in different pixel areas. The light shielding portion includes a red filter layer laminated with the blue filter unit, and a blue filter layer laminated with the green filter unit and the red filter unit. That is, if the filter layer corresponding to the spacer opposite-top region is a red filter unit, the light shielding portion extending toward the filter layer is a green filter layer, and if the filter layer corresponding to the spacer opposite-top region is a green filter unit or a blue filter unit, the light shielding portion extending toward the filter layer is a red filter layer.
Fifth embodiment:
referring to fig. 11, the present embodiment provides a display panel 200, which includes a counter substrate 220, an array substrate 100, and a liquid crystal layer 230. The counter substrate 220 is disposed opposite to the array substrate 100. The liquid crystal layer 230 is interposed between the opposite substrate 220 and the array substrate 100.
