Problems solved by technology

However, for narrow-frame products with a frame less than 2.4mm, there is a risk that the alignment film prepared by the inkjet printing process will completely cover the bonding electrodes.
Because the alignment film is an insulating material, the alignment film covering the binding electrode will cause poor conduction between the COF and the binding electrode, resulting in abnormal display

Abstract

The present application discloses a liquid crystal display device, comprising: an array substrate and a color filter substrate disposed opposite to each other, and a liquid crystal layer and spacer columns interposed therebetween. The liquid crystal display device includes a display area and a non-display area. A binding area is also provided in the non-display area, a binding electrode is formed on the array substrate located in the binding area, and a first alignment film is also provided on the array substrate; wherein, the binding A first barrier is provided on the electrode near the edge of the display area, and the first barrier is used to separate the first alignment film from the binding electrode. In the embodiment of the present application, by setting a retaining wall structure between the alignment film on the array substrate side and the binding electrodes, it is possible to prevent the inkjet ink for preparing the alignment film from covering the binding electrodes, and to prevent poor conduction between the COF substrate and the binding electrodes.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] In a thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD), a chip on film substrate (Chip On Film, COF) is usually used to connect a printed circuit board (PCB) and a liquid crystal panel together, Therefore, the PCB board can output the driving control signal to the liquid crystal panel to complete the corresponding driving control. One end of the COF substrate is bonded to a bonding electrode (bonding lead) of the array substrate, and the other end of the COF substrate is connected to the PCB board. [0003] In the current liquid crystal display device, an alignment film is provided on the side of the array substrate, which can provide a pre-tilt angle for the liquid crystal molecules, so that the liquid crystal molecules are arranged in an orderly manner. T...
