THIN-FILM TRANSISTOR AND ORGANIC LIGHT-EMITTING DISPLAY DEVICE INCLUDING THE SAME
First Claim
1. A thin-film transistor comprising:
- a gate electrode disposed on a substrate;
a first insulating layer disposed on the gate electrode;
an active layer disposed on the first insulating layer and corresponding to the gate electrode;
a second insulating layer disposed on the first insulating layer and covering the active layer, the second insulating layer comprising first and second openings exposing first and second portions of the active layer, respectively;
a source electrode disposed on the second insulating layer and connected to the first portion of the active layer via the first opening of the second insulating layer;
a drain electrode disposed on the second insulating layer and connected to the second portion of the active layer via the second opening of the second insulating layer; and
a dummy member disposed on the second insulating layer to correspond to at least a third portion of the active layer between the first and second portions of the active layer.
