Embodiment Construction

[0045] For a liquid crystal display device (a liquid crystal panel or a display device) driven by a transverse electric field, both the pixel electrodes and the common electrodes are located on the array substrate, wherein the pixel electrodes or the common electrodes are slit electrodes located on the outermost layer of the array substrate. Since the black matrix of the color filter substrate is an incomplete insulator, under the action of the capacitor effect, the black matrix can sense the voltage on the slit electrode and accumulate a certain charge. Specifically, when the pixel electrodes are located on the outermost layer of the array substrate, the black matrix can sense the voltage on the pixel electrodes; when the common electrodes are located on the outermost layer of the array substrate, the black matrix can sense the voltage on the common electrodes.

[0046] When the part of the black matrix is ​​located in the non-display area, it is easy to be grounded or exposed...

Abstract

The invention relates to the technical field of liquid crystal display and discloses a color film substrate and a display device. For a display device with a transverse electric field as a driving electric field, when the black matrix of the color film substrate is located within the part of a non-display region, the black matrix is arranged to comprise a portion to be connected, and a preset voltage is applied to the black matrix by virtue of the portion to be connected to ensure that the differential pressure of the black matrix and a pixel electrode or the differential pressure of the black matrix and a common electrode during dark state display is low and not enough to drive liquid crystal molecules to deflect, and therefore, the poor greening phenomenon during dark state display is overcome and the yield and the display quality of the product are improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, no radiation, and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. Liquid crystal panel is an important part of liquid crystal display, combined with figure 1 and figure 2 As shown, it includes a color filter substrate 1 and an array substrate 2 arranged in opposite boxes, and forms a sealed space between the color filter substrate 1 and the array substrate 2 through a sealant 4' for filling liquid crystals. Wherein, a black matrix 3 is formed on the color filter substrate, which is used to define a plurality of sub-pixel areas in the display area 100, and a filter layer (such as: red filter layer 31, g...
