The main spacer 32M is disposed between the first substrate 10 and the second substrate 20. In addition, the display panel 1 of the present embodiment can further include at least one pair of spacers 32S disposed between the first substrate 10 and the second substrate 20, for example, on the second substrate 20. In the present embodiment, the definition of the main spacer 32M refers to the fact that the display panel 1 is in a normal state, which is in contact with the first substrate 10 and the second substrate 20 at the same time, or simultaneously with the film layer on the first substrate 10. The film layers on the second substrate 20 are in contact such that a fixed gap can be maintained between the first substrate 10 and the second substrate 20. The definition of the sub spacer 32S means that the display panel 1 is in a normal condition (a state in which no deformation or compression by an external force is applied), which is not in contact with the first substrate 10 or the film layer on the first substrate 10, but is subjected to In the case where the external force is pressed, the sub spacer 32S can be in contact with the first substrate 10 or the film layer on the first substrate 10, whereby the display panel 1 can be prevented from being excessively deformed and damaged. In general, the main spacer 32M and the sub spacer 32S are disposed on the same substrate, for example, the second substrate 20, and the height of the main spacer 32M may be greater than the height of the sub spacer 32S, thereby the main interval under normal conditions. The object 32M is in contact with the first substrate 10 or its upper film layer and the sub spacer 32S is not in contact with the first substrate 10 or its upper film layer. In a variant embodiment, the height of the main spacers 32M may be substantially equal to the height of the sub spacers 32S, but the film layers on the first substrate 10 corresponding to the positions of the main spacers 32M and the sub spacers 32S may have different heights. Thereby, the main spacer 32M is in contact with the first substrate 10 or its upper film layer under normal conditions, and the sub spacer 32S does not come into contact with the first substrate 10 or its upper film layer.

The light shielding pattern layer 34 has at least one protruding portion 34S, wherein the main spacer 32M is correspondingly partially overlapped with the protruding portion 34S of the light shielding pattern layer 34 in a vertical projection direction Z, and the projected area of the protruding portion 34S in the vertical projection direction Z Greater than the projected area of the main spacer 32M in the vertical projection direction Z. That is, the projected area of the main spacer 32M can be completely covered by the projected area of the protruding portion 34S as viewed from the vertical projection direction Z, whereby the protruding portion 34S can ensure that the light leakage around the main spacer 32M can be completely Shaded. In this embodiment, the light shielding pattern layer 34 may be disposed on the second substrate 20 or may be disposed on the first substrate 10. The material may be an opaque material such as black ink or black photoresist material (also referred to as a black matrix). ), but not limited to this. Further, the arrangement positions of the switching elements of the display panel 1, the wires such as the gate lines, the data lines, the common lines, and the like may be changed in accordance with the position of the light shielding pattern layer 34. In another variation, the light shielding pattern layer 34 may also be disposed on the first substrate 10, and the material thereof may be an opaque material such as a black ink or a black photoresist material (also referred to as a black matrix), or may be any insulation. Or conductive opaque material. In addition, one of the second substrate 20 or the first substrate 10 may be further provided with a color filter layer CF such as a red filter layer, a green filter layer and a blue filter layer.

The pixel array AR is disposed on the first substrate 10, and the pixel array AR includes a plurality of sub-pixels SP, wherein the sub-pixels SP are arranged in a plurality of sub-pixel columns PR arranged along a first direction D1, and a plurality of pixels A sub-pixel line PC arranged in a second direction D2. The sub-picture line PC includes a plurality of first picture lines PC1 and a plurality of second picture lines PC2, and the first picture line PC1 and the second picture line PC2 have substantially the same length in the second direction D2. In addition, each pixel The PS is substantially a rectangular sub-pixel, wherein the rectangular sub-pixel has a major axis direction Lx substantially parallel to the second direction D2, and a minor axis direction Sx is substantially parallel to the first direction D1. It is worth noting that the corners of a part of the sub-pixels SP are occupied by the light-shielding pattern layer 34, but the sub-pixels SP are substantially rectangular. In this embodiment, the number of the first pixel rows PC1 is two, and the remaining pixels of the pixel row PC is the second pixel row PC2, but not limited thereto. The number of the first pixel row PC1 and the second pixel row PC2 can be changed depending on the number and size of the main spacers 32M. The light shielding pattern layer 34 further includes a first body portion 341 disposed between two adjacent sub-pixel rows PR, and the protruding portion 34S and the first body portion 341 are connected to each other and overlap in the first direction D1. The first body portion 341 and the second pixel row PC2 overlap in the second direction D2, and the protruding portion 34S of the light shielding pattern layer 34 overlaps with the first pixel row PC1 in the second direction D2, and the protruding portion 34S is in the The width w1 in the two directions D2 is larger than the width w2 of the first body portion 341 in the second direction D2. Since the width w1 of the protruding portion 34S is larger than the width w2 of the first body portion 341, the area of the sub-pixel SP adjacent to the protruding portion 34S in the second direction D2 is occupied by the protruding portion 34S, that is, The aperture ratio of the sub-pixel SP adjacent to the protrusion 34S in the second direction D2 may be smaller than the aperture ratio of the other sub-pixels SP. For example, the aperture ratio of the four sub-pixels SP around the main spacer 32M is smaller than the aperture ratio of all other sub-pixels SP, so that the brightness of the four sub-pixels SP is significantly lower than other times. The brightness of the pixel SP causes the brightness of the display panel 1 to be uneven. The aperture ratio of all the sub-pixels SP of the first pixel row PC1 of the embodiment is smaller than the aperture ratio of the sub-pixels SP of the second pixel row PC2, so that the aperture ratio between the different pixels SP can be reduced. The difference, in turn, solves the problem of uneven brightness. To be precise, in the present embodiment, all of the secondary pixels SP of the first pixel row PC1 have substantially the same aperture ratio.

In this embodiment, the light shielding pattern layer 34 further includes a second body portion 342 and a first offset portion 34A disposed between the other two adjacent pixel groups PR in the first direction D1. That is, the first body portion 341 and the second body portion 342 are substantially parallel to each other and are respectively disposed between different adjacent sub-pixel columns PR. The first offset portion 34A and the second body portion 342 are in the second direction D2 The upper portion has substantially the same width, wherein the first offset portion 34A overlaps with the first pixel row PC1 in the second direction D2, and the second body portion 342 overlaps with the second pixel row PC2 in the second direction D2. And the second body portion 342 and the first offset portion 34A are connected to each other in the first direction D1 and do not completely overlap. That is, the first offset portion 34A is offset in the direction away from the protruding portion 34S in the second direction D2 with reference to the second body portion 342. Therefore, the length L1 of each pixel SP of the first pixel row PC1 in the second direction D2 is smaller than the length L2 of the second pixel SP2 of the second pixel row PC2 in the second direction D2, and the first The width S1 of each pixel SP of the sub-picture line PC1 in the first direction D1 and the width S2 of the respective pixels SP of the second pixel line PC2 in the first direction D1 are substantially equal. With the above arrangement, all the sub-pixels SP of the first pixel row PC1 will have the same aperture ratio, and all the sub-pixels SP of the second pixel row PC2 will have the same aperture ratio. Although the aperture ratio of the sub-pixel SP of the first pixel PC1 is smaller than the aperture ratio of the sub-pixel SP of the second pixel PC2, the aperture ratio of the sub-pixel SP of the first pixel PC1 is the second. The difference in aperture ratio of the sub-pixel SP of the sub-picture line PC2 is reduced, and the brightness distribution of the display panel 1 is relatively uniform.

Please refer to Figure 4. Fig. 4 is a view showing the aperture ratio distribution of the display panel of the first embodiment. First, in a comparative embodiment, the aperture ratio of all the sub-pixels SP of the second pixel row PC2 and the aperture ratio of the sub-pixel SP of the first pixel row PC1 not adjacent to the main spacer 32M are 100%, The aperture ratio of the four sub-pixels SP adjacent to the main spacer PC1 and the main spacer 32M is 88%. That is, in the comparative embodiment, the difference between the aperture ratio of the four sub-pixels SP adjacent to the main spacer 32M and the aperture ratio of all the sub-pixels SP not adjacent to the main spacer 32M reaches 12%. And the distribution of the four sub-pixels SP having a low aperture ratio is too concentrated, so the brightness of the four sub-pixels SP is significantly different from the brightness of the other sub-pixels SP, and the display panel is formed in this area. dark spot. As shown in FIG. 4, in the first embodiment, the aperture ratio of all the sub-pixels SP of the second pixel row PC2 is 100%, and the aperture ratio of all the sub-pixels SP of the first pixel row PC1 is 94. %, at this time, the second pixel is the aperture ratio of the secondary pixel SP of PC2 and the first pixel line PC1 The difference in aperture ratio of the sub-pixel SP is only 6%, and the distribution of the sub-pixels SP having a low aperture ratio is relatively dispersed, so that the problem of uneven brightness can be effectively improved. It should be noted that the aperture ratio of all the sub-pixels SP of the first pixel row PC1 of the embodiment is not limited to 94%, and the size and proportion of the visible display panel 1 and the area of the shading pattern layer 34 and the sub-picture It is adjusted by factors such as the area of the SP. Further, all of the sub-pixels SP of the first pixel row PC1 of the present embodiment have substantially the same aperture ratio, but basically allow a certain degree of error. For example, the aperture ratio of all sub-pixels SP of the first pixel row PC1 may allow an error of ±1%. In general, when the difference in aperture ratios of the different sub-pixels SP of the display panel 1 is less than or equal to 6%, preferably less than 5%, more preferably less than 3%, the user does not easily observe the brightness.
