Abstract

The invention discloses a display panel, a display device and a making photomask thereof. The display panel comprises a first substrate, a second substrate, a liquid crystal layer, multiple grooves and spacers; the second substrate is arranged to be opposite to the first substrate; the liquid crystal layer is formed between the first substrate and the second substrate; the grooves are formed in the first substrate and concaved into the surface of the first substrate; the spacers are formed on the first substrate and arranged between the first substrate and the second substrate; the spacers comprise the main spacer and the auxiliary spacers, the main spacer is higher than the auxiliary spacers, and the auxiliary spacers are located in the grooves. In this way, the auxiliary spacers are fixed into the grooves, segment gaps between the auxiliary spacers and the main spacer can be increased, liquid crystal redundancy of a liquid crystal box is increased, and the phenomenon that due to temperature change, the liquid crystal box is prone to nonuniform gravity displayer brightness can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a photomask for making the same. Background technique [0002] The cell thickness of a liquid crystal display (Liquid Crystal Display, TFT-LCD) is determined by the amount of liquid crystal injected into it, and the volume of the liquid crystal will be affected by the ambient temperature. When the high temperature causes the volume of the liquid crystal to increase, the liquid crystal cell is prone to uneven brightness (Mura); when the low temperature causes the volume of the liquid crystal to shrink, the liquid crystal cell is prone to vacuum bubbles (Bubble). In the liquid crystal cell, there are two photosensitive spacers (Photo Spacer, PS), one is the main photosensitive spacer (Main-PS) that maintains the thickness of the liquid crystal cell under normal circumstances, and the other is to receive external force extrusion Auxiliary phot...
