The spacer 217 is located on the same surface of the color filter substrate 210 as the first black matrix 214 and the second black matrix 215. That is, the spacer 217 and the first black matrix 214 and the second black matrix 215 are located on the same surface of the color filter substrate 210. In this embodiment, since the first black matrix 214 and the second black matrix 215 are located on the first surface 210a of the color filter substrate 210, the spacer 217 is located on the color filter substrate. On the first surface 210a of 210. When the first black matrix 214 and the second black matrix 215 are located on the second surface 210b of the color filter substrate 210, the spacer 217 is located on the second surface of the color filter substrate 210. On 210b.
相较于现有技术，本发明的彩色滤光基板210的位于所述边框区域212 的第二黑矩阵215的高度大于位于所述显示区域211的第一黑矩阵214的高度，从而使得所述彩色滤光基板210在后续形成透明导电层的时候，透明导电层不容易破裂且使得具有所述彩色滤光基板210的液晶显示面板的漏光减少。且所述第二黑矩阵215的高度大于或等于所述第一黑矩阵214的高度的两倍，使得所述第一黑矩阵214上设置滤光单元213之后更加平整，使得在后续形成透明导电层的时候，透明导电层更加不容易破裂，从而使得包括所述彩色滤光基板210的液晶显示面板20具有更好的品质。Compared with the prior art, the color filter substrate 210 of the present invention is located in the frame region 212. The height of the second black matrix 215 is greater than the height of the first black matrix 214 located in the display region 211, so that when the color filter substrate 210 is subsequently formed into a transparent conductive layer, the transparent conductive layer is not easily broken and The light leakage of the liquid crystal display panel having the color filter substrate 210 is reduced. The height of the second black matrix 215 is greater than or equal to twice the height of the first black matrix 214, so that the filter unit 213 is disposed on the first black matrix 214 to be more flat, so that transparent conductive is formed later. At the time of the layer, the transparent conductive layer is less likely to be broken, so that the liquid crystal display panel 20 including the color filter substrate 210 has better quality.
