ABSTRACT:
Provided is a flat panel display in which no stripes appear on a screen, thereby improving image quality. The flat panel display has a matrix-type array of sub-pixels, each of which includes a driving thin film transistor, a first electrode driven by the driving thin film transistor, and a second electrode driving a light emission unit together with the first electrode. The driving thin film transistor includes semiconductor channels which are derived from a semiconductor layer. Heterogeneous straight lines are separated from each other on the semiconductor layer. An imaginary line connecting the semiconductor channels of one column is not parallel to the heterogeneous straight lines.
