Patent ID: 8651910

Claim:
A method of fabricating a top emission type organic electroluminescent display device, comprising: forming a switching thin film transistor and a driving thin film transistor in a pixel region on a first substrate; forming a passivation layer over the switching thin film transistor and the driving thin film transistor, the passivation layer having a drain contact hole exposing a drain electrode of the driving thin film transistor; forming a first electrode on the passivation layer and connected to the drain electrode of the driving thin film transistor; forming a buffer pattern in a border of the pixel region and overlapping an edge of the first electrode; forming a first spacer on the buffer pattern along a first direction, the first spacer having a first thickness and a dam shape; forming a second spacer on the buffer pattern along a second direction, the second spacer having a second thickness and a dam shape; forming a third spacer on the buffer pattern at a crossing portion of the first and second spacers, the third spacer having a third thickness and a columnar shape, wherein the third thickness is thicker than the first thickness or the second thickness; forming an organic emission layer on the first electrode between adjacent buffer patterns; forming a second electrode on the organic emission layer and the first, second and third spacers; and disposing a transparent second substrate over the first substrate and attaching the first substrate and the second substrate such that a seal pattern is formed between the first and second substrates along peripheries of the first and second substrates.
