Display substrate, manufacturing method thereof and display device
First Claim
1. A display substrate, comprising a plurality of pixel regions and a thin film transistor provided in each of the pixel regions, wherein, each of the pixel regions comprises a transmissive region and a reflective region, a protection layer is provided on the thin film transistor, a portion of the protection layer corresponding to the reflective region is a protrusion portion, and a portion of the protection layer corresponding to the thin film transistor is provided with a via therein;
- wherein the protrusion portion is configured to ensure that an optical path of light passing through the reflective region is equal to an optical path of light passing through the transmissive region;
wherein a color resist layer is provided above the protrusion portion and extends to the transmissive region, and a thickness of a portion of the color resist layer corresponding to the transmissive region is twice as large as that of a portion of the color resist layer corresponding to the reflective region; and
wherein a pixel-electrode layer is provided on the color resist layer, and is electrically connected to a drain of the thin film transistor through the via provided in the protection layer.
