ABSTRACT:
The display device includes a first substrate, a second substrate, a spacer and a connection electrode. The first substrate includes an organic electroluminescence diode device, and the second substrate faces the first substrate and includes a thin film transistor. The connection electrode is configured to electrically connect the thin film transistor and the organic electroluminescence diode device. The display device further includes a first buffer pattern configured to separate two adjacent pixel regions and a second buffer pattern overlying the first buffer pattern and having a predetermined shape. The first buffer pattern is etchable to produce a cavity between the two adjacent pixel regions. The cavity can be enlarged to the extent that the shape of the second buffer pattern is maintained.
