Organic light-emitting display

An organic light-emitting display comprising:

• a thin film transistor comprising:
• a gate electrode;
• an active layer electrically insulated from the gate electrode;
• a source electrode and a drain electrode electrically insulated from the gate electrode, and contacting the active layer;
• and
• an insulating layer formed between i) the source and drain electrodes and ii) the active layer;
• and
• an organic light-emitting device electrically connected to the thin film transistor,
• wherein the source electrode comprises a first source electrode and a second source electrode that are separated from each other, and a third source electrode electrically connecting the first and second source electrodes, and wherein the drain electrode comprises a first drain electrode and a second drain electrode that are separated from each other, and a third drain electrode electrically connecting the first and second drain electrodes,
• wherein the third source electrode includes a first portion which is substantially directly above a first edge of the gate electrode, wherein the third drain electrode includes a second portion which is substantially directly above a second edge of the gate electrode opposing the first edge, and wherein the first and second portions of the third source and drain electrodes are substantially parallel with the gate electrode.
