Abstract
The present disclosure relates to a display substrate. The display substrate may include a base substrate, a light filtering layer on the base substrate, a plurality of light blocking grooves in the light filtering layer, and a plurality of light blocking strips in the plurality of light blocking grooves respectively. The plurality of light blocking strips may be configured to block light from viewing angles outside a visible range of the display substrate.
Claims20
A display substrate, comprising:
- a base substrate,
- a light filtering layer on the base substrate,
- a plurality of light blocking grooves in the light filtering layer, and
- a plurality of light blocking strips in the plurality of light blocking grooves respectively,
- wherein the plurality of light blocking strips are configured to block light from viewing angles outside a visible range of the display substrate.
A method of fabricating a display substrate, comprising:
- providing a base substrate;
- forming a light filtering layer on the base substrate;
- performing a first patterning process on the light filtering layer, thereby forming a plurality of light blocking grooves in the light filtering layer;
- covering the light filtering layer with a layer of light blocking material, wherein a portion of the light blocking material is filled into the light blocking grooves;
- and
- removing the layer of light blocking material outside the light blocking grooves, thereby forming a plurality of light blocking strips.
