Organic electroluminescent display device and method of fabricating the same

Abstract

A top emission type organic electroluminescent display device includes a first substrate including a pixel region, a switching thin film transistor and a driving thin film transistor in the pixel region on the first substrate, a passivation layer covering the switching thin film transistor and the driving thin film transistor and exposing a drain electrode of the driving thin film transistor, a first electrode on the passivation layer and connected to the drain electrode of the driving thin film transistor, a buffer pattern in a border of the pixel region and overlapping an edge of the first electrode, a first spacer on the buffer pattern along a first direction, the first spacer having a first thickness and a dam shape, a second spacer on the buffer pattern along a second direction, the second spacer having a second thickness and a dam shape, 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, an organic emission layer on the first electrode between adjacent buffer patterns, a second electrode on the organic emission layer and the first, second and third spacers, a second substrate facing the first substrate, and a seal pattern between peripheries of the first and second substrates.
