Abstract

The invention discloses a liquid crystal display panel, comprising a first substrate, a color filter layer, a second substrate, and a plurality of spacers. The color filter layer is arranged on the first substrate. A plurality of longitudinally arranged data lines and a plurality of horizontally arranged scanning lines are formed in the color filter layer, and the plurality of scanning lines and the plurality of data lines are interlaced with each other. The color filter layer is arranged on the first substrate, and a plurality of through holes are formed in the color filter layer. The plurality of spacers are arranged on the color filter layer and include at least one flow guide spacer. At least one surface tension elimination ridge line is formed on the flow guide spacer for eliminatingthe surface tension of alignment liquid and causing the alignment liquid to smoothly flow into the plurality of through holes. The flow guide spacer can improve the yield and the quality of the liquidcrystal display panel.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel, in addition to the main spacer provided between the two glass substrates of the liquid crystal display panel, there is also a flow guide spacer adjacent to the via hole (Via), In this way, the surface tension of the polyimide (Polyimide, PI) alignment liquid is eliminated, so that the PI alignment liquid can smoothly flow into the via hole. Background technique [0002] Existing liquid crystal display products with color filter array (Color Filter On Array, COA) substrates use a large number of 3T structure technology and organic insulating film array (Polymer Film On Array, PFA) technology, must be in the Cell of the liquid crystal display panel The PI coating process uses polyimide (Polyimide, PI) alignment liquid. However, the PI alignment liquid has high surface tension and is easy to condense and unfavorable to flow, which will easily...
