Abstract

A liquid crystal display device comprises a colored-film substrate, an array substrate and a liquid crystal layer. The colored-film substrate comprises a first substrate, a color-blocking layer, a block matrix and a shielding layer, wherein the color-blocking layer, the block matrix and the shielding layer are arranged on the first substrate. The array substrate is opposite to the colored-film substrate and comprises a second substrate, a pixel electrode, a public electrode and an insulation layer located between the pixel electrode and the public electrode, wherein the pixel electrode and the public electrode are arranged on the second substrate. A control signal for driving foreign ions in the liquid crystal layer to be detained is loaded on the shielding layer and is a periodic alternating-current voltage signal, the frequency of the signal is higher than or equal to the refresh rate of the liquid crystal display device, and the control signal is synchronous with the refresh of the liquid crystal display device. The control signal is loaded on the shielding layer of the colored-film substrate of the liquid crystal display device and produces an electric field in the liquid crystal display device, so that the probability that foreign ions in the liquid crystal layer are absorbed on the array substrate is reduced. Accordingly, the liquid crystal display device can perform normal display and is low in cost and short in consumed time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy saving, no radiation, etc., therefore has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Generally, a liquid crystal display includes a color filter substrate, an array substrate, and a liquid crystal layer located between the color filter substrate and the array substrate. A plurality of cross-insulated scanning lines and data lines, pixel electrodes, common electrodes and a plurality of transistor elements are arranged on the array substrate, wherein the scanni...
