Abstract
The present disclosure relates to an array substrate and a method for manufacturing the same. The array substrate includes a substrate having first regions for forming pixels and second regions located between the first regions, light shielding portions located within portions of the second regions adjacent to the first regions on the substrate, and pixel defining portions located within the second regions. At least a side surface of the light shielding portion adjacent to the first region is not covered by the pixel defining portion.
Claims14
An array substrate comprising:
- a substrate having first regions for forming pixels and second regions located between the first regions;
- light shielding portions located within portions of the second regions adjacent to the first regions on the substrate;
- pixel defining portions located within the second regions;
- and
- a conductive layer located on the substrate and located between the pixel defining portions,
- wherein at least a side surface of the light shielding portion adjacent to the first region is not covered by the pixel defining portion,
- wherein the second region comprises a central region and a peripheral region surrounding the central region,
- wherein the light shielding portion is located only within the peripheral region,
- wherein an entire lower surface of the light shielding portion, an entire lower surface of the pixel defining portion, and an entire lower surface of the conductive layer are flush with each other, and
- wherein an entire upper surface of the conductive layer is not covered by the light shielding portion and the pixel defining portion,
- wherein an orthographic projection of the conductive layer on the substrate doesn't overlap with an orthographic projection of the light shielding portion on the substrate and an orthographic projection of the pixel defining portion on the substrate, and
- wherein an area of the conductive layer along a plane parallel to the substrate is equal to an area of the first region and less than an area of an opening region defined by the pixel defining portion.
