Abstract

The embodiment of the invention discloses a liquid crystal display device, and belongs to the technical field of liquid crystal display. The liquid crystal display device comprises an array substrate, a color filer substrate, a printed circuit board and a flexible circuit board. The color filter substrate is arranged opposite to the array substrate, and the array substrate comprises a plurality of first public electrodes and a first public electrode connecting wire. The color filter substrate comprises a second public electrode, the printed circuit board comprises a first resistor, a second resistor and a chip, the printed circuit board is connected with the array substrate through the flexible circuit board, the chip provides a first public voltage for the first public electrodes through the first resistor and the flexible circuit board, and the chip provides a second public voltage for the second public electrode through the second resistor and the flexible circuit board. The picture incidental image condition of the liquid crystal display device can be avoided, and the display quality of the liquid crystal device can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and currently occupies a dominant position in the field of flat panel display. Liquid crystal display devices are very suitable for application in various office automation and audio-visual equipment such as desktop computers, palmtop computers, personal digital assistants (Personal Digital Assistant, PDA), portable phones, and television boxes. A liquid crystal display panel is a main component of a liquid crystal display device. Generally, a liquid crystal display panel includes an array substrate, a color filter substrate and a liquid crystal layer, and the liquid crystal layer is disposed between the array su...
