Abstract
An organic light emitting diode display includes a first electrode, a pixel defining layer positioned on the first electrode and including a first opening having a first polygonal shape opening the first electrode, and a first organic emission layer positioned on the pixel defining layer through the first electrode corresponding to the first opening and including a first chamfer adjacent to a corner of the first opening.
Claims21
An organic light emitting diode display, comprising:
- a first electrode;
- a second electrode spaced apart from the first electrode;
- a third electrode spaced apart from the first electrode;
- a pixel defining layer positioned on the first electrode, the second electrode, and the third electrode, the pixel defining layer including a first opening, a second opening, and a third opening respectively corresponding to the first electrode, the second electrode, and the third electrode;
- a first organic emission layer, a second organic emission layer, and a third organic emission layer respectively overlapping the first electrode, the second electrode, and the third electrode,
- wherein:
- the first organic emission layer is positioned on the pixel defining layer across the first electrode corresponding to the first opening and includes a first convex portion being pointed to by an adjacent corner of the first opening;
- the first electrode and the second electrode are alternately disposed in a first direction;
- the first electrode and the second electrode are alternately disposed in a second direction perpendicular to the first direction;
- the first electrode and the third electrode are alternately disposed in a third direction different from the first direction and the second direction;
- and
- a virtual line connecting a central point of the first electrode and a central point of the third electrode is parallel to the third direction and oblique to the first direction and the second direction.
