Abstract
An organic light emitting display device includes a via pattern including a first surface parallel to a top surface of a substrate and a second surface being inclined with respect to the top surface of the substrate at a predetermined angle, a first electrode disposed on the via pattern and including an inclined portion which has an end portion being toward the substrate, and a black matrix located on the second electrode.
Claims22
An organic light emitting display device comprising:
- a substrate;
- a via pattern disposed on the substrate, the via pattern including a first surface parallel to a top surface of the substrate and a second surface located at both sides of the first surface, the second surface being inclined with respect to the top surface of the substrate at a predetermined angle;
- a first electrode disposed on the first and second surfaces of the via pattern, the first electrode including an inclined portion overlapping with the second surface of the via pattern, with an end portion of the inclined portion being toward the substrate;
- a light emitting layer disposed on the first electrode;
- a second electrode disposed on the light emitting layer;
- and
- a black matrix located on the second electrode.
A method of manufacturing an organic light emitting display device, the method comprising:
- preparing a substrate;
- forming a via pattern on the substrate to include a first surface parallel to a top surface of the substrate and a second surface located at both sides of the first surface, the second surface being inclined with respect to the top surface of the substrate at a predetermined angle;
- forming a first electrode overlapped with the second surface, the first electrode disposed on the first and second surfaces of the via pattern and including an inclined portion, with an end portion of the inclined portion being toward the substrate;
- forming a light emitting layer on the first electrode;
- forming a second electrode on the light emitting layer;
- and
- forming a black matrix on the second electrode.
An organic light emitting display device comprising:
- a substrate;
- a first electrode disposed on the substrate and including a horizontal top surface in parallel with a top surface of the substrate, and two inclined side surfaces respectively located at two opposite sides of the horizontal top surface of the first electrode, each of the two inclined side surfaces being inclined with respect to the top surface of the substrate at a predetermined angle and extending from the horizontal top surface of the first electrode with an end portion toward the substrate;
- a light emitting layer disposed on the first electrode;
- a second electrode disposed on the light emitting layer;
- and
- a black matrix located on the second electrode and not overlapped with the first electrode.
