Problems solved by technology

However, with the higher resolution of the display panel, that is, the higher the pixel per inch (ppi), the size of each pixel becomes smaller and smaller, and the average rotation angle of the liquid crystal molecules will be affected by the data lines on both sides and the common electrode. And the influence of the electric field of the transparent electrode makes the average rotation angle of the liquid crystal molecules deviate from 45 degrees, resulting in a decrease in the transmittance of the display panel

Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate opposite the first substrate and a pixel array. The pixel array is arranged between the first substrate and the second substrate and comprises at least one pixel; the pixel has an electrode layer and a data line arranged on the side, facing the second substrate, of the first substrate; the substrate layer comprises a first main electrode and a plurality of branch electrodes; the first main electrode extends in the first direction and intersects the data line, and is connected with the branch electrodes; the branch electrodes extend in the second direction; at least an angle of y is formed between the second direction and the first direction; y is greater than B1 and less than A1. The equation of A1 is A1=-1.28*10<5>(x)<3>+0.0047722(x)<2>-0.383068 (x)+59.494865, and the equation of B1 is B1=-2.38*10<5>(x)<3>+0.0093751(x)<2>-1.098394(x)+81.919357; y is greater than 45 degrees and is not greater than 70 degrees, and x represents the number of pixels per inch of the display panel.

Description

technical field [0001] The present invention relates to a display panel and a display device, in particular to a display panel and a display device capable of improving transmittance. Background technique [0002] With the advancement of technology, flat panel display devices have been widely used in various fields, especially liquid crystal display devices, which have gradually replaced traditional cathode ray tube display devices due to their superior characteristics such as light and thin body, low power consumption and no radiation. , and applied to many kinds of electronic products, such as mobile phones, portable multimedia devices, notebook computers, LCD TVs and LCD screens, etc. [0003] At present, manufacturers of liquid crystal display devices are improving the wide viewing angle technology (Multi-domain Vertical Alignment, MVA) of thin-film transistor liquid crystal display devices (TFTLD). Mature optical performance and mass production technology. Among them,...
