Abstract
The present disclosure provides an electroluminescent display apparatus including a substrate including a first subpixel, a second subpixel, and a third subpixel, a first electrode in each of the first subpixel, the second subpixel, and the third subpixel on the substrate, a bank provided in a boundary between any two of the first subpixel, the second subpixel, and the third subpixel to cover an edge of the first electrode, a protection layer on the first electrode and the bank, a light emitting layer on the protection layer, and a second electrode on the light emitting layer.
Claims15
An electroluminescent display apparatus comprising:
- a first pixel including a first subpixel emitting light of a first color, a second subpixel emitting light of a second color, and a third subpixel emitting light of a third color, the first pixel being provided in a substrate;
- a second pixel including a first subpixel emitting light of the first color, a second subpixel emitting light of the second color, and a third subpixel emitting light of the third color, the second pixel being provided in the substrate;
- a first electrode in each of the first subpixel, the second subpixel, and the third subpixel in each of the first pixel and the second pixel;
- a protection layer on the first electrode in each of the first subpixel, the second subpixel, and the third subpixel in each of the first pixel and the second pixel;
- a light emitting layer on the protection layer;
- and
- a second electrode on the light emitting layer,
- wherein the protection layer comprises a first portion overlapping the first subpixel in each of the first pixel and the second pixel, a second portion overlapping the second subpixel in each of the first pixel and the second pixel, a third portion overlapping the third subpixel in each of the first pixel and the second pixel, a fourth portion overlapping a boundary between any two of the first subpixel, the second subpixel, and the third subpixel in each of the first pixel and the second pixel, and a fifth portion overlapping a boundary between the first pixel and the second pixel;
- and
- wherein a thickness of the first portion is thicker than a thickness of the second portion, a thickness of the second portion is thicker than a thickness of the third portion, and a thickness of the third portion is thicker than a thickness of the fourth portion.
