Description

LCD panel

The present invention relates to a liquid crystal display panel.

The liquid crystal in the liquid crystal display panel itself does not have the illuminating property, and the backlight module or the like is used to provide planar light for the liquid crystal display panel and to control the twisting of the liquid crystal molecules by the electric field to realize the passage or non-passing of the light, thereby achieving the purpose of display. The liquid crystal display panel generally includes two substrates disposed opposite to each other and a liquid crystal layer sandwiched between the two substrates, wherein a spacer (Spacer) for maintaining a distance between the two substrates is further disposed between the two substrates. However, the presence of spacers may cause the arrangement of nearby liquid crystal molecules to become disordered, causing light leakage and reducing the contrast of the panel. Therefore, it is generally required to completely block the spacer and a portion of its periphery by using a black matrix to avoid light leakage of the panel. The method also leads to a decrease in the aperture ratio and the transmittance of the liquid crystal display panel, resulting in poor display performance.

In view of the above, it is necessary to provide a liquid crystal display device having a high aperture ratio.

A liquid crystal display panel includes a first substrate, a second substrate disposed opposite the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate, the first substrate including a plurality of first driving lines a plurality of second driving lines that are insulated from the first driving line, and a plurality of pixel regions, the plurality of first driving lines being divided into a plurality of pairs, each pair of first driving lines including two first driving lines disposed adjacent to each other The complex pixel region is divided into a plurality of pairs, each pair of pixel regions being sandwiched between adjacent two second driving lines and including The first pixel area and the second pixel area are disposed adjacent to each other, and the first pixel area and the second pixel area of each pair of pixel areas are respectively located on two sides of the corresponding pair of first driving lines, and each The second driving line includes an overlapping portion overlapping each pair of first driving lines and a main portion connecting the overlapping portions, the liquid crystal display panel further including a first portion between the first substrate and the second substrate a spacer, the second substrate includes a black matrix, the black matrix includes a first portion overlapping each pair of first driving lines and a second portion overlapping the main portion, the first view from a direction perpendicular to the liquid crystal display panel A spacer overlaps the first portion.

Compared with the prior art, the liquid crystal display panel of the present invention sets adjacent two first driving lines of each pair, and the first pixel area and the second pixel area are respectively located on both sides of each pair of first driving lines. Seen from a direction perpendicular to the liquid crystal display panel, the first spacer is disposed corresponding to the first portion of the black matrix overlapping each pair of first driving lines, since each pair of first driving lines is originally configured to avoid reflection of the driving lines The black matrix occlusion is required, so that the first spacer is further disposed corresponding to the first portion of each pair of the first driving lines corresponding to the occlusion of the black matrix, and the first spacer can be completely blocked without substantially increasing the black matrix area. Further, the liquid crystal display panel has a higher aperture ratio and a better display effect. In addition, since the two first driving lines of each pair are adjacent to each other, and the overall area of the first portion of the black matrix that blocks the two first driving lines together is large, the black matrix area can be substantially increased without increasing the black matrix area. The first spacer forms a more effective occlusion, and the liquid crystal display panel can maintain a higher aperture ratio, and the display effect is better.

In the present embodiment, the first spacer 34, the third spacer 35, and the second spacer 36 have the same extension length. Since the third spacer 35 corresponds to the overlapping portion 3120 of the second driving line 312, the distance between the first spacer 34 and the first substrate 31 is greater than the distance between the third spacer 35 and the first substrate 31. The distance between the third spacer 35 and the first substrate 31 is smaller than the distance between the second spacer 36 and the first substrate 31, because the second spacer 36 corresponds to the spacer region 310 and the notch 3113.
