View Patent ↗An organic electroluminescent device includes first and second substrates facing and spaced apart from each other, the first and second substrates including a pixel region; a gate line on an inner surface of the first substrate; a data line crossing the gate line; a switching thin film transistor connected with the gate line and the data line; a driving thin film transistor connected with the switching thin film transistor; a power line connected with the driving thin film transistor; a first electrode on an inner surface of the second substrate; a first sidewall and a second sidewall on the first electrode at a boundary of the pixel region, the first sidewall and the second sidewall spaced apart from each other; an electroluminescent layer on the first electrode in the pixel region; a second electrode on the electroluminescent layer in the pixel region; and a connection electrode electrically connected to the first and second substrates.
1. A substrate for an organic electroluminescent device, comprising:
a substrate including a pixel region;
a first electrode on an entire inner surface of the substrate;
first and second sidewalls on the first electrode at a boundary of the pixel region, the first and second sidewalls spaced apart from each other, wherein the first and second sidewalls each have negative and positive sloped sides that are substantially parallel, and wherein the negative sloped sides of the first and second sidewalls are disposed at inside to face each other and the positive sloped sides of the first and second sidewalls are disposed at outside;
electroluminescent layers on the first electrode in the pixel region; and
a second electrode on the electroluminescent layers in the pixel region.
2. A method of fabricating a substrate for an organic electroluminescent device, comprising:
forming a first electrode on a substrate having a pixel region;
forming first and second sidewalls spaced apart from each other on the substrate at a boundary of the pixel region, wherein the first and second sidewalls each have negative and positive sloped sides that are substantially parallel, and wherein the negative sloped sides of the first and second sidewalls are disposed at inside to face each other and the positive sloped sides of the first and second sidewalls are disposed at outside;
forming an electroluminescent layer on the first electrode in the pixel region; and
forming a second electrode on the electroluminescent layer in the pixel region.
