Abstract
An organic light emitting diode includes a plurality of bank portions and light emitting parts formed between the bank portions wherein the bank portions have stepwise portions at ends thereof extending to the light emitting parts. The exemplary embodiments of an organic light emitting diode according to the present invention have droplets deposited in a wider space between the bank portions, and adjacent pixels are prevented from contacting each other and being shorted out.
Claims4
An organic light emitting diode comprising:
- a plurality of bank portions;
- and
- light emitting parts formed between the bank portions,
- wherein the bank portions have stepwise portions at ends thereof extending to the light emitting part.
A method of manufacturing an organic light emitting diode, comprising:
- forming a plurality of bank portions;
- and
- forming light emitting parts between the bank portions,
- wherein the forming of the bank portions comprises;
- forming a photoresist layer;
- preparing a mask having an exposing region, a shadowing region, and slits between the exposing region and the shadowing region;
- exposing the photoresist layer to an ultraviolet light source through the mask;
- and
- developing the exposed photoresist layer to form bank portions having stepwise portions in a region corresponding to the slits.
