通过上述设置方式,也可以在一定程度上改善色偏现象。Through the above setting method, the color cast can also be improved to a certain extent.
根据主干部对R、G、B三原色影响程度的差异,可以选择上述 任一实施例的设置方式来设置遮光层40。本申请对上述遮光层40的各种设置方式均进行试验,发现将第二像素电极132和第三像素电极133上的主干部采用遮光层40进行遮挡,第一像素电极131上的主干部不设置遮光层40,以此来达到的色偏改善效果最好。According to the difference in the degree of influence of the main stem on the three primary colors of R, G, and B, the light-shielding layer 40 can be arranged in any of the above-mentioned arrangement modes. This application has tested various arrangements of the above-mentioned light-shielding layer 40, and found that the main part on the second pixel electrode 132 and the third pixel electrode 133 is shielded by the light-shielding layer 40, and the main part on the first pixel electrode 131 is not The shading layer 40 is provided to achieve the best color cast improvement effect.
如表1所示,为遮光层40遮挡前后,红色像素单元(R)、绿色像素单元(G)、以及蓝色像素单元(B)的亮度变化比例关系,该实验中,所有像素电极13的狭缝角均为45度,对比不设置遮光层40,和第二像素电极132和第三像素电极133上的主干部采用遮光层40进行遮挡、第一像素电极131上的主干部不设置遮光层40这两种情况。As shown in Table 1, the ratio of brightness changes of the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) before and after the shielding layer 40 is shielded.

由表1可知,第二像素电极132和第三像素电极133上的主干部采用遮光层40进行遮挡、第一像素电极131上的主干部不设置遮光层40时,侧视时红色像素单元(R)、绿色像素单元(G)、以及蓝 色像素单元(B)的亮度比例均有不同程度的变化,其中颜色B的亮度变化最明显;将绿色像素单元(G)和蓝色像素单元(B)的主干部采用遮光层40遮挡之后,红色像素单元(R)、绿色像素单元(G)、以及蓝色像素单元(B)的亮度变化幅度下降,其中颜色B的亮度变化幅度下降的最明显。It can be seen from Table 1 that when the trunk portions on the second pixel electrode 132 and the third pixel electrode 133 are shielded by the light shielding layer 40, and the trunk portion on the first pixel electrode 131 is not provided with the light shielding layer 40, the red pixel unit ( R), the green pixel unit (G), and the blue pixel unit (B) have different brightness ratios. Among them, the brightness of color B has the most obvious change; the green pixel unit (G) and the blue pixel unit ( After the main part of B) is shielded by the light-shielding layer 40, the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) have reduced brightness changes. Among them, the brightness change of color B has the greatest decrease. obvious.
相对于整个像素电极13均不设置遮光层40的情况,将绿色像素单元(G)和蓝色像素单元(B)的主干部采用遮光层40遮挡之后,侧视时各像素单元的亮度变化幅度均有所减小,即遮光层40的设置改善了液晶显示面板的色偏现象。Compared with the case where the entire pixel electrode 13 is not provided with the light-shielding layer 40, after the main parts of the green pixel unit (G) and the blue pixel unit (B) are shielded by the light-shielding layer 40, the brightness change range of each pixel unit in side view Both are reduced, that is, the arrangement of the light shielding layer 40 improves the color shift of the liquid crystal display panel.
此外,通过合理设置像素电极13的狭缝角的角度,也可以在一定程度上改善了色偏现象。In addition, by reasonably setting the angle of the slit angle of the pixel electrode 13, the color shift phenomenon can also be improved to a certain extent.
如图2所示,由于像素电极13的狭缝角越大,液晶显示面板的透光率越好,但色偏情况也越严重,相反,像素电极13的狭缝角越小,色偏情况也越少,但液晶显示面板的透光率会变差。因此,需要将像素电极13的狭缝角设置为一个合理的角度,既能保证透光率,又能减小色偏。同时,在对应像素电极13主干部的区域设置遮光层40,两者一起作用,进一步减小色偏现象。As shown in Figure 2, since the larger the slit angle of the pixel electrode 13, the better the light transmittance of the liquid crystal display panel, but the more serious the color shift. On the contrary, the smaller the slit angle of the pixel electrode 13, the better the color shift. It is also less, but the light transmittance of the liquid crystal display panel will deteriorate. Therefore, it is necessary to set the slit angle of the pixel electrode 13 to a reasonable angle, which can ensure the light transmittance and reduce the color shift. At the same time, a light-shielding layer 40 is provided in the region corresponding to the backbone of the pixel electrode 13, and the two work together to further reduce the color shift.

在一种实施例中,第一夹角θ 1小于或等于45度,第三夹角θ 3大于或等于35度。 In an embodiment, the first included angle θ 1 is less than or equal to 45 degrees, and the third included angle θ 3 is greater than or equal to 35 degrees.
本实施例中,将第一夹角θ 1设置为45度,第二夹角θ 2设置 为40度,第三夹角θ 3设置为35度,以此来达到的色偏改善效果最好。 In this embodiment, the first included angle θ 1 is set to 45 degrees, the second included angle θ 2 is set to 40 degrees, and the third included angle θ 3 is set to 35 degrees, which achieves the best color shift improvement effect. .
需要说明的是,本申请不限于此,狭缝角也可以设置为其他的角度,只要减小色偏的同时能保证一定的透光率即可。It should be noted that the present application is not limited to this, and the slit angle can also be set to other angles, as long as the color shift can be reduced while ensuring a certain light transmittance.
