Mask for manufacturing double-domain electrode, double-domain electrode and display panel

Abstract

The invention discloses a mask for manufacturing a double-domain electrode, the double-domain electrode and a display panel. The mask comprises a plurality of shading strips and light-transmitting strips located between various shading strips; each shading strip comprises a first body part extending along a first direction, a second body part extending along a second direction, a first connectingpart extending along a third direction and a second connecting part extending along a fourth direction; the first body part is connected with the first connecting part; the second body part is connected with the second connecting part; the first connecting part is connected with the second connecting part; and a concave pattern is arranged on the inner side of an included angle between the first connecting part and the second connecting part, and / or a first convex pattern is arranged on the outer side of the included angle. The exposure amount at the inner side of the included angle is increased through the concave pattern, and / or the exposure amount at the outer side of the included angle is reduced through the first convex pattern, so that corners of the double-domain electrode manufactured by using the mask are relatively sharper, so that a Trace mura phenomenon is effectively avoided while ensuring the transmittance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate for making a double-domain electrode, a double-domain electrode and a display panel. Background technique [0002] The fringe field switching (Fringe Field Switching, FFS) display technology is the mainstream display technology in the current LCD wide viewing angle display. Its main principle is to use the electric field in the horizontal direction to control the liquid crystal deflection, so that the maximum viewing angle can be close to 90°. Specifically, the electric field controlling the liquid crystal deflection is formed by the voltage difference between the pixel electrode and the common electrode. At the same time, in order to improve the color shift, the pixel electrode and / or the common electrode is designed as a slit dual-domain electrode structure in the industry. And in the double-domain electrode structure, the domains in two directions form a small ...

However, if still using Figure 4 If the mask shown in the figure is used to make a dual-domain electrode, the exposure amount will be insufficient due to the small pattern of the mask used to make a smaller corner, so that the corner in the final double-domain electrode is as follows Figure 5 rounded corners as shown, and cannot be formed as image 3 The sharp corners shown result in less control over the Trace mura and lower display quality
