Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic plan view showing a display panel 100 of the present utility model. Fig. 4 is a cross-sectional view showing an embodiment of the vicinity of the buffer area 20 of the display panel 100 of the present utility model. As shown in fig. 1 and 4, the display panel 100 includes a substrate 10, a black matrix layer 11 formed on the substrate 10, and a color resist layer 12 formed on the black matrix layer 11. A display area a and a non-display area NA are formed on the display panel 100. In the present embodiment, the display area a has a rectangular shape, and the non-display area NA has a frame shape surrounding the display area a. In the non-display area NA, the color resist layer 12 is provided with a buffer area 20 and a barrier area 30. The buffer 20 is disposed to surround the display area a. Likewise, the barrier region 30 is also disposed to surround the display area a. In addition, the barrier 30 also surrounds the buffer 20. That is, the buffer area 20 is closer to the display area a than the barrier area 30.
In this embodiment, there is a certain distance between the buffer area 20 and the blocking area 30. However, the buffer zone 20 may be closely attached to the barrier zone 30 in other embodiments. That is, buffer zone 20 is zero-spaced from barrier zone 30.
As shown in fig. 1, the non-display area NA is further provided with a glue frame 40. The glue frame 40 surrounds the barrier region 30. That is, the glue frame 40 is disposed on the side of the blocking area 30 away from the buffer area 20.
Fig. 2 is a partial enlarged view showing an embodiment of the buffer 20 of the display panel of the present utility model. The buffer zone 20 comprises at least one buffer leg 21. Each buffer leg 21 includes a plurality of buffer cells 211. The plurality of buffer units 211 are spaced apart and arranged in a line shape. In the present embodiment, as shown in fig. 2, the buffer area 20 includes three buffer branches 21 parallel to each other, and the buffer unit 211 has a rectangular shape. Further, the plurality of buffer units 211 are formed of color resistors, in this embodiment, red, blue, and green.
Preferably, as shown in fig. 2, the openings between the buffer cells 211 of one buffer leg 21 are not aligned with the openings between the buffer cells 211 of an adjacent other buffer leg 21, i.e., the buffer cells 211 of a first buffer leg 21 are offset from the buffer cells 211 of a second buffer leg 21. This enhances the buffer effect of the buffer 20 on the alignment liquid 50.
As described above, the buffer unit 211 of the embodiment shown in fig. 2 is formed of red, blue, green, but is not limited thereto, and as shown in (a) of fig. 3, the buffer unit 211 may be formed of only blue. It is understood that the buffer unit 211 may be formed of one or more color resists.
As described above, the buffer unit 211 of the embodiment shown in fig. 2 is rectangular, but is not limited thereto, and as shown in (b) of fig. 3, the buffer unit 211 may also be triangular. As shown in fig. 3 (d), the buffer unit 211 may also have a polygonal shape, such as pentagon and hexagon. As shown in fig. 3 (e), the buffer unit 211 may also be a combination of various shapes.
Fig. 4 is a cross-sectional view showing an embodiment of the buffer area 20 of the display panel 100 of the present utility model. As shown in fig. 4, the display panel 100 includes a substrate 10, a black matrix layer 11 formed on the substrate 10, and a color resist layer 12 formed on the black matrix layer 11. That is, the black matrix layer 11 is formed between the substrate 10 and the color resist layer 12. In this embodiment, the buffer area 20 of the color resist layer 12 includes two buffer branches 21. Two adjacent buffer legs 21 are spaced apart from each other and arranged in parallel, that is, in the buffer zone 20, the buffer legs 21 are in a peak configuration and the spacing between adjacent buffer legs 21 is in a valley configuration. Two buffer legs 21 are formed on the black matrix layer 11. As a result, as shown in fig. 4, when the alignment liquid 50 flows (the direction in which the alignment liquid 50 flows is indicated by two arrows in the figure) to the buffer area 20, at least a part of the alignment liquid stays in the valley structure, so that the flow to the frame 40 is reduced, and the frame 40 is prevented from being contaminated.
Fig. 5 is a cross-sectional view showing a modification of the buffer 20 of fig. 4. The structure of this modification is basically the same as that of fig. 4, except for the shape of the black matrix layer 11. As shown in fig. 5, in this modification, the portion of the black matrix layer 11 overlapping the valley structure between the two buffer branches 21 is formed to have a plurality of elongated wavy portions 111 arranged at intervals, so that more alignment liquid 50 can be retained than in the embodiment shown in fig. 4. Likewise, the direction in which the alignment liquid 50 flows is indicated by two arrows in the figure.
Fig. 6 is a partial enlarged view showing a plurality of embodiments of the barrier region 30 of the display panel 100 of the present utility model. The blocking area 30 comprises at least one blocking leg 31. The blocking branch line 31 is formed in a continuous strip shape for blocking the flow of the alignment liquid 50 toward the rubber frame 40. And, the blocking branch line 31 is formed of a color resist. In the various embodiments shown in fig. 6, the blocking area 30 comprises three blocking branches 31. As shown in fig. 6 (a), the blocking leg 31 is formed of a blue resistor. As shown in fig. 6 (b), the blocking branch line 31 is formed of red color resist. As shown in fig. 6 (c), the blocking leg 31 is formed of a green resistor. As shown in fig. 6 (d), the three blocking branches 31 are formed of red, blue, and green, respectively. As shown in fig. 6 (e), two of the three blocking branches 31 are formed of green color resist and one is formed of red color resist. It will be appreciated that the blocking leg 31 may be formed from one or more color resists.
Fig. 7 is a cross-sectional view showing an embodiment of the display panel 100 of the present utility model in the vicinity of the barrier region 30. As shown in fig. 7, in the present embodiment, the blocking area 30 of the color resist layer 12 includes two blocking branches 31. The two blocking legs 31 are spaced apart from each other and arranged in parallel, that is, in the blocking region 30, the blocking legs 31 serve as peak structures and the spacing between the blocking legs 31 serve as valley structures. In the present embodiment, the black matrix layer 11 is not provided at a position overlapping with the valley structure between the barrier branch lines 31. That is, the black matrix layer 11 is provided only at a portion overlapping with the blocking branch line 31. It will be appreciated that the valley structure of the black matrix layer 11 is superimposed between the barrier region 30 and the barrier leg 31 such that the alignment liquid 50 will remain in the superimposed valley structure when flowing to the barrier region 30, thereby avoiding flowing to the glue frame 40 and contaminating the glue frame 40.
Fig. 8 is a cross-sectional view showing an embodiment of the vicinity of the buffer area 20 and the barrier area 30 of the display panel 100 of the present utility model. As shown in fig. 8, in this embodiment, there is a certain space between the buffer region 20 and the blocking region 30. The alignment liquid 50 flows from one side of the buffer area 20 near the display area a towards the glue frame 40, a part of the alignment liquid 50 is retained in the valley structure of the buffer area 20, a part of the alignment liquid 50 is retained between the buffer area 20 and the blocking area 30, and the rest of the alignment liquid 50 is retained in the valley structure of the blocking area 30, so that the alignment liquid 50 is prevented from flowing to the glue frame through the structures of the buffer area 20 and the blocking area 30, the glue frame is polluted, the solidification of the glue frame is affected, and the yield of the display panel is improved.
