Description

Color film substrate with staggered BM at edge and display device

Technical Field

The utility model belongs to the technical field of display devices, and particularly relates to a color film substrate with staggered BM at the edge and a display device.

Background

The structure of the liquid crystal display panel mainly comprises a Thin Film transistor (Thin Film TransistorArray, TFTArray) substrate, a Color Filter (CF) substrate and a liquid crystal layer (LiquidCrystalLayer) arranged between the two substrates, and the working principle is that the rotation of liquid crystal molecules of the liquid crystal layer is controlled by applying driving voltage on the two substrates, so that the light rays of the backlight module are refracted to generate pictures.

In the process of manufacturing the liquid crystal display panel, a plurality of BM (black matrix) grooves (as shown in fig. 1 and 2) are designed around the display area (AA) (i.e. the non-display area), and the BM grooves are disposed on the non-display area of the CF substrate. According to different designs, the BM grooves are filled with different color resistance layers, but a small part of light leakage is unavoidable or edge red lines are caused by filling the BM grooves with color resistance. With the popularity of narrow bezel, the liquid crystal display panel boundary is getting smaller. The method is limited by the boundary width of the liquid crystal display panel, so that the width of the metal wiring on the TFT substrate can be designed to be very narrow, and the liquid crystal on the liquid crystal layer shifts the group precision, so that the risk that the metal wiring on the TFT substrate can not completely shield light leakage exists, and therefore, the liquid crystal display panel has the risks of edge red line occurrence probability, light leakage, yield reduction and the like.
