Problems solved by technology

According to the change of the fixed direction, the amount of phase delay Δnd will increase or decrease, and the transmittance of light waves of different colors will change accordingly, so the picture will appear color shift, which will lead to poor viewing angle of the display panel and even lead to gray scale reversal. change

Abstract

The invention relates to a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a plurality of sub-pixels defined by a plurality of scanning lines and a plurality of data lines in a cross mode and arranged in array, and neighboring 2X2 sub-pixels of different colors form a pixel; each sub-pixel comprises a plurality of strip electrodes, the plurality of strip electrodes of the sub-pixels of neighboring rows respectively extend towards a first direction and second direction, and the first direction and the second direction respectively incline to the clockwise direction and the anti-clockwise direction of the scanning lines to form a first angle; the sub-pixels of the same row comprise the sub-pixels of four different colors; in the neighboring two rows of the sub-pixels, at least one strip electrode of the sub-pixels of the same color extends to the first direction and at least one trip electrode extends to the second direction. The liquid crystal display panel and the liquid crystal display device can improve color error and gray scale inversion and preferably reduces the probability of transverse and longitudinal stripes production and improves display quality.

Description

technical field [0001] The invention relates to the display field, in particular to a liquid crystal display panel and a liquid crystal display device including the liquid crystal display panel. Background technique [0002] Flat panel displays are popular due to their thinness, power saving and other advantages, among which liquid crystal display devices are the most common. A liquid crystal display panel generally includes an array substrate, a color filter substrate, and a liquid crystal layer filled between the array substrate and the color filter substrate. At least one of the array substrate and the color filter substrate is formed with a pixel electrode and a common electrode, and an electric field is formed between the pixel electrode and the common electrode when power is applied, and the orientation angle of the liquid crystal molecules is modulated by controlling the change of the electric field intensity, thereby making the backlight The light transmittance chan...
