Abstract
A display substrate, a method of fabricating the same and a display device are provided. The display substrate includes a substrate and a groove formed on the substrate. The groove is formed by photoresist and the bottom surface of the groove exceeds a height of a pixel area.
Claims15
A display panel, comprising:
- a substrate;
- a first groove and a second groove formed on the substrate, wherein the first groove and the second groove are formed by photoresist and bottom surfaces of the grooves exceed a height of a pixel area on the substrate, and wherein a spacer block is provided in the bottom of the first groove;
- an opposite substrate;
- and
- a spacer structure formed on the opposite substrate corresponding to the grooves formed on the substrate, wherein the spacer structure comprises a main spacer received in the first groove with the spacer block therein and a secondary spacer received in the second groove, to allow the secondary spacer not to contact the substrate when the main spacer contacts the spacer block,
- wherein the second groove comprises a plurality of grooves with different heights.
