Problems solved by technology

However, for a horizontal electric field type liquid crystal display device, the electric field distribution in the liquid crystal layer is not uniform, and there is a local area not covered by the electric field, which cannot transmit light, resulting in low overall transmittance of the liquid crystal panel.

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] refer to image 3 According to the structure of the existing horizontal electric field liquid crystal panel, the pixel electrode a and the common electrode b are formed on the array substrate 1 , and no electrode structure is formed on the color filter substrate 2 . From image 3 It can be seen from the figure that after the voltage is applied, a horizontal electric field 4 will be formed between the pixel electrode a and the common electrode b, but no electric field will be formed in the area above the pixel electrode a and the common electrode b, so that the liquid crystal molecules in the upper area Rotation cannot occur, and no phase delay occurs when the light passes through this region. Under the action of the upper and lower polarizer...

Abstract

The invention provides a color film substrate, a liquid crystal panel and a liquid crystal display device which belong to the field of liquid crystal displaying. The liquid crystal panel comprises an array substrate, the color film substrate and a liquid crystal layer which is formed between the array substrate and the color film substrate, wherein one side of the array substrate which faces to the color film substrate is provided with a plurality of first pixel electrodes and first common electrodes which are lined alternatively; one side of the color film substrate which faces to the array substrate is provided with a plurality of groups of electrode structures; each group of electrode structure comprises a second pixel electrode and a second common electrode; and the second pixel electrode and the second common electrode in each group of electrode structure are symmetrically distributed on both sides of the orthographic projection of each first pixel electrode or each first common electrode on the color film substrate. According to the color film substrate, the liquid crystal panel and the liquid crystal display device, the transmissivity of the liquid crystal panel can be improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a color filter substrate, a liquid crystal panel and a liquid crystal display device. Background technique [0002] Liquid crystal display devices are classified into vertical electric field type liquid crystal display devices and horizontal electric field type liquid crystal display devices according to the direction of an electric field for driving liquid crystals. Vertical electric field type liquid crystal display devices mainly include twisted nematic (TN) mode and vertical alignment (VA) mode, and horizontal electric field type liquid crystal display devices mainly include in-plane switching (IPS) mode, boundary field switching (FFS) mode and advanced ultra-dimensional field switch (ADS) mode. Compared with the vertical electric field type liquid crystal display device, the horizontal electric field type liquid crystal display device does not need an additional optica...
