Abstract

The invention discloses a circuit substrate, a display panel and a display device, wherein the circuit substrate is used for a display panel, the circuit substrate includes a shielding electrode and a pixel electrode, and the pixel electrode includes at least two kinds of branch electrodes with different extending directions. An electrode, wherein the first branch electrode extends longitudinally along the long side direction of the pixel electrode, the first branch electrode includes an overlapping area and a non-overlapping area, the overlapping area is opposite to the shielding electrode, and the non-overlapping area Adjacent to the shielding electrode, the width of the non-overlapping region is greater than or equal to a first preset value, so as to reduce signal coupling between the shielding electrode and the pixel electrode. The technical scheme of the invention avoids the generation of dark lines at the edges of pixels, and improves the transmittance of the display panel.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a circuit substrate, a display panel and a display device. Background technique

[0002] Currently, liquid crystal display panels on the mainstream market can be divided into three types, namely twisted nematic (Twisted Nematic, TN) or super twisted nematic, in-plane switching (In-Plane Switching, IPS) and vertical alignment (Vertic Alignment). , VA) type. A liquid crystal display device generally includes a backlight module, a circuit substrate and a color filter substrate oppositely arranged, and liquid crystals filled between the circuit substrate and the color filter substrate. In the process of curing the liquid crystal to form a pre-tilt angle, the signal coupling between the pixel electrode and the shielding electrode on the circuit substrate is likely to cause the tilt of the liquid crystal molecules to be affected by the shielding electrode, and dark lines are generate...
