At present, as a currently mainstream flat panel display mode, a liquid crystal display device has advantages of light weight, thin thickness, low power consumption, and the like, and is widely used in modern signal devices such as televisions, computers, mobile phones, digital cameras, and the like. As shown in fig. 1, a top view of a high pixel density liquid crystal display panel 100' in the related art is shown. Fig. 2a is a schematic diagram showing a structure in which the counter substrate of the liquid crystal display panel is shifted to the right with respect to the array substrate, and fig. 2b is a schematic diagram showing a structure in which the counter substrate of the liquid crystal display panel is shifted to the left with respect to the array substrate.

As shown in fig. 1, the liquid crystal display panel 100 ' includes an array substrate 110 ', a counter substrate (not shown) and a liquid crystal layer (not shown) disposed between the array substrate 110 ' and the counter substrate, the array substrate 110 ' includes a gate line 111 ', a data line 112 ', a thin film transistor 113 ' and a pixel electrode 114 ', a plurality of gate lines and a plurality of data lines are disposed on the array substrate 110 ' to cross each other to define a plurality of sub-pixel regions 115 ', a thin film transistor 113 ' and a pixel electrode 114 ' are disposed in each sub-pixel region 115 ', a drain 1131 ' of the thin film transistor 113 ' is connected to the pixel electrode 114 ', the counter substrate includes a light shielding layer 121 ' and a plurality of sub-pixel light-transmitting regions 122 ' defined by the light shielding layer 121 ', and the plurality of sub-pixel regions 115 ' and the plurality of sub-pixel light-transmitting regions 122 ' are in one-to-one correspondence. In order to maintain the thickness of the liquid crystal display panel 100 ' uniform (i.e., the thickness of the liquid crystal layer is substantially uniform), it is generally necessary to provide spacers 130 ' on the opposite substrate side facing the array substrate 110 '. For example, as shown in fig. 1, the surface of the spacer 130 'facing the array substrate 110' is in contact with the data line provided on the array substrate 110 ', and functions to position the thickness of the liquid crystal display panel 100'.

It should be understood that the spacer 130 ' may be abutted against the gate line or the thin film transistor 113 ' of the array substrate 110 ' in addition to the data line 112 ' of the array substrate 110 '. A Main spacer and an auxiliary spacer are disposed between the array substrate 110' and the opposite substrate, the Main spacer is usually in the form of a support column called Main support column (Main-PS), and correspondingly, the auxiliary spacer may also be in the form of a support column called auxiliary support column (Sub-PS), and the height of the auxiliary spacer is smaller than that of the Main spacer. The spacer in the related art is referred to as a main spacer.

However, for the lcd panel with high pixel density, since the sub-pixels are smaller, the size of the single spacer 130 ' is smaller, when the lcd panel 100 ' is pressed, the relative displacement, i.e., the Shift (Shift), between the array substrate 110 ' and the opposite substrate in the direction parallel to the display panel easily occurs, and at this time, the spacer 130 ' is easily marked into the sub-pixel light-transmitting region 122 ', so that the alignment layer PI on the array substrate 110 ' located in the sub-pixel region 115 ' is damaged, the alignment disorder occurs, the normal display of the sub-pixel is affected, and PS Mura (for example, expressed as red/blue spots) occurs. In order to improve PS Mura, a peripheral Black Matrix (BM) of a spacer is usually widened, a sliding boundary (Margin) of the spacer is increased, for example, as shown in fig. 1, a corner of the black matrix, which is close to the spacer 130 ', is increased and reflected on a sub-pixel light-transmitting area 122 ' defined by the black matrix, that is, the sub-pixel light-transmitting area 122 ' is in an asymmetric structure, so that when the liquid crystal display panel is pressed, an array substrate and a counter substrate slide left/right, there is a large difference in the area of shielding the adjacent two sub-pixel light-transmitting areas 122 ' by a data line, that is, the difference in transmittance of the adjacent two sub-pixel light-transmitting areas 122 ' is large, so that the liquid crystal display panel 100 ' has obvious color shift, and the display quality of the liquid crystal display panel 100 ' is reduced.

Based on the above-mentioned problems, the present application provides a display panel and a display device, so as to improve the color shift problem of the display panel after being pressed due to widening of the black matrix, and improve the display quality of the display panel.

As shown in fig. 3, an embodiment of the first aspect of the present application provides a display panel 100, including an array substrate 110 and an opposite substrate (not shown) disposed opposite to the array substrate; the array substrate 110 includes a plurality of gate lines 111, a plurality of data lines 112, a plurality of sub-pixel regions 115 defined by the intersections of the plurality of gate lines 111 and the plurality of data lines 112, and a thin film transistor 113 and a pixel electrode 114 within each sub-pixel region, the thin film transistor 113 including a drain electrode 1131 connected to the pixel electrode 114; the opposite substrate comprises a light shielding layer 121 and a plurality of sub-pixel light transmission areas 122 defined by the light shielding layer 121, wherein the sub-pixel light transmission areas 122 are in one-to-one correspondence with the sub-pixel areas 115; in the direction in which the gate line 111 extends, each three sub-pixel regions 115 forms one pixel region 140, and when the drain electrode 1131 slides between the array substrate 110 and the opposite substrate along the gate line 111 in at least one sub-pixel region 115 of the pixel region 140, the orthographic projection of the drain electrode 1131 on the opposite substrate overlaps with the corresponding or adjacent sub-pixel light transmitting region 122.

In the display panel 100 provided by the embodiment of the application, the plurality of sub-pixel regions 115 and the plurality of sub-pixel light-transmitting regions 122 are in one-to-one correspondence up and down, the thin film transistor 113 and the pixel electrode 114 are disposed in each sub-pixel region 115, the thin film transistor 113 includes the drain electrode 1131 connected with the pixel electrode 114, and each three sub-pixel regions 115 form one pixel region 140 along the extending direction of the gate line 111, and when the drain electrode 1131 slides between the array substrate 110 and the opposite substrate along the direction of the gate line 111 in at least one sub-pixel region 115 of the pixel region 140, the orthographic projection of the drain electrode 1131 on the opposite substrate is partially overlapped with the corresponding or adjacent sub-pixel light-transmitting region 122. In this way, when the display panel 100 slides along the gate line direction, the overlapping portion of the drain electrode 1131 and the sub-pixel light-transmitting region 122 compensates for the area difference of the adjacent two sub-pixel light-transmitting regions 122 blocked by the data line 112, so as to reduce the area difference of the adjacent two sub-pixel light-transmitting regions 122 blocked by the data line 112, further improve the color shift problem of the display panel 100 after being pressed due to the widening of the light shielding layer 121, and improve the display quality of the display panel 100.

In some embodiments of the present application, the sub-pixel light transmissive region 122 includes a first boundary 1221 adjacent to the drain electrode 1131; the drain electrode 1131 includes a second boundary 1131-1 adjacent to the sub-pixel light transmitting region 122, the second boundary 1131-1 coinciding with the first boundary 1221. In this way, the area of the drain electrode 1131 is increased, when the first boundary 1221 of the sub-pixel light-transmitting region 122 and the gate line 111 have non-parallel sections, and the array substrate 110 and the opposite substrate slide along the direction of the gate line 111, the orthographic projection of the drain electrode 1131 in the sub-pixel region 115 on the opposite substrate may partially overlap with the corresponding sub-pixel light-transmitting region 122, so as to compensate the area difference of the adjacent two sub-pixel light-transmitting regions 122 blocked by the data line 112, and further improve the color cast problem of the display panel 100 after being pressed due to the widening of the light shielding layer 121, and improve the display quality of the display panel 100.

In some embodiments of the present application, within at least one subpixel region 115, a second boundary 1131-1 of drain electrode 1131 exists for a section that is not parallel to gate line 111. Since the second boundary 1131-1 of the drain electrode 1131 coincides with the first boundary 1221 of the sub-pixel light-transmitting region 122, when the second boundary 1131-1 of the drain electrode 1131 has a section that is not parallel to the gate line 111, the first boundary 1221 of the sub-pixel light-transmitting region 122 also has a section that is not parallel to the gate line 111, so that when the array substrate 110 and the opposite substrate slide along the gate line 111, the front projection of the drain electrode 1131 in the sub-pixel region 115 on the opposite substrate may partially overlap with the corresponding sub-pixel light-transmitting region 122, thereby compensating the area difference of the two adjacent sub-pixel light-transmitting regions 122 blocked by the data line 112, and further improving the color cast problem of the display panel 100 after being pressed due to the widening of the light-shielding layer 121, and improving the display quality of the display panel 100.

In some embodiments of the present application, the areas of the drain electrode 113 in at least two sub-pixel regions 115 are different in the pixel region 140. Since the second boundary 1131-1 of the drain electrode 1131 coincides with the first boundary 1221 of the sub-pixel light-transmitting region 122, when the areas of the drain electrodes 113 in the at least two sub-pixel regions 115 are different, the distances from the first boundary 1221 of the at least two sub-pixel light-transmitting regions 122 to the gate line 111 are different, so that when the array substrate 110 and the opposite substrate slide along the gate line 111, the orthographic projection of the drain electrode 1131 in the sub-pixel region 115 on the opposite substrate can partially overlap with the adjacent sub-pixel light-transmitting regions 122, thereby compensating the difference of the areas of the adjacent two sub-pixel light-transmitting regions 122 blocked by the data line 112, further improving the color cast problem of the display panel 100 after being pressed due to the widening of the light shielding layer 121, and improving the display quality of the display panel 100.

In some embodiments of the present application, the sub-pixel light transmissive region 122 further includes a third boundary 1222 opposite the first boundary 1221, the third boundary 1222 having a section non-parallel to the gate line 111. Thus, the light shielding layer 121 can be widened along the direction of the data line 112, so that the sliding boundary of the spacer is increased, and the PS Mura is effectively improved.

In some embodiments of the present application, in the pixel region 140, the three sub-pixel regions 115 are a first color sub-pixel region, a second color sub-pixel region, and a third sub-pixel region, respectively, the first, second, and third color sub-pixel regions are sequentially distributed along the extending direction of the gate line 111, a first section non-parallel to the gate line 111 exists at a second boundary of the drain electrode in the first color sub-pixel region, a second section non-parallel to the gate line 111 exists at a second boundary of the drain electrode in the second color sub-pixel region, and the first section is adjacent to the second section. It should be understood that the first color sub-pixel region may be a red sub-pixel region, the second color sub-pixel region may be a blue sub-pixel region, and the third color sub-pixel region may be a green sub-pixel region. Since the human eyes are most sensitive to green, the spacers are generally located between the red and blue sub-pixels, that is, the spacers are located between the first color sub-pixel region and the second color sub-pixel region, and the second boundary of the drain electrode in the first color sub-pixel region has a first section non-parallel to the gate line 111, and the second boundary of the drain electrode in the second color sub-pixel region has a second section non-parallel to the gate line 111, and the first section and the second section are distributed adjacently, so that not only the sliding boundary of the spacers can be increased, but also the PS Mura can be effectively improved, and the orthographic projection of the drain electrode 1131 in the sub-pixel region 115 on the opposite substrate can be partially overlapped with the corresponding sub-pixel light-transmitting region 122 when the array substrate slides relative to the opposite substrate, so as to compensate the difference of the areas of the adjacent two sub-pixel light-transmitting regions 122, which are blocked by the data line 112, thereby improving the color shift problem of the display panel 100 after being pressed due to widening the light shielding layer 121, and improving the display quality of the display panel 100.

In some embodiments of the application, the area of the drain electrode in the third color sub-pixel region is larger than the areas of the drain electrodes in the first red sub-pixel region and the second sub-pixel region. In this way, when the array substrate 110 slides along the gate line direction relative to the opposite substrate, the difference of the areas of the three sub-pixel light transmitting areas corresponding to the first to third color sub-pixel areas blocked by the data lines can be reduced, so as to improve the color cast problem of the display panel 100.

In some embodiments of the present application, the drain electrode in the third sub-pixel region has a convex shape, and the convex portion of the drain electrode faces the sub-pixel light transmitting region 122. In this way, when the array substrate 110 slides along the gate line direction relative to the opposite substrate, the difference of the areas of the three sub-pixel light transmitting areas corresponding to the first to third color sub-pixel areas blocked by the data line can be further reduced, so as to effectively improve the color cast problem of the display panel 100.

In some embodiments of the present application, the light shielding layer 121 may be a black matrix.

In some embodiments of the present application, the array substrate 110 includes a first substrate and a common electrode, the thin film transistor 113 is disposed on the first substrate, the thin film transistor 113 further includes a gate electrode, an active layer, and a source electrode, the gate line is connected to the gate electrode, the source electrode is connected to the data line, and the common electrode and the pixel electrode are disposed opposite to each other. The first substrate base plate is typically made of glass.

In some embodiments of the present application, a PVX protective layer is disposed between the common electrode and the pixel electrode 114.

In some embodiments of the present application, the opposite substrate further includes a second substrate and a color resist unit, the light shielding layer 121 is disposed on a side of the second substrate, which is close to the array substrate 110, the color resist unit is disposed in the sub-pixel light-transmitting region, the color resist unit may include a first color resist, a second color resist, and a third color resist, the first color resist may be a red resist, the second color resist may be a green resist, and the third color resist may be a blue resist.

In some embodiments of the present application, a liquid crystal layer is disposed between the array substrate 110 and the opposite substrate.
