Dual-panel type organic electroluminescence display device comprises connection electrode to electrically connect thin film transistor and organic electroluminescence diode device located in respective substrates, and two buffer patterns

摘要

A display device comprises a first substrate (100) including an organic electroluminescence diode device (E); a second substrate (200) facing the first substrate and including a thin film transistor; a connection electrode (245) to electrically connect the thin film transistor and the organic electroluminescence diode device; a first buffer pattern (115) to separate two adjacent pixel regions; and a second buffer pattern (125) overlying the first buffer pattern, and having a predetermined shape. A display device comprises a first substrate including an organic electroluminescence diode device; a second substrate facing the first substrate and including a thin film transistor; a connection electrode to electrically connect the thin film transistor and the organic electroluminescence diode device; a first buffer pattern 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 disposed between the two adjacent pixel regions; and the cavity can be enlarged to the extent that the shape of the second buffer pattern is maintained. An independent claim is included for a method of fabricating a display device.
