摘要： In a light emitting display and a fabrication method thereof, a stripe pattern displayed due to characteristic differences of a driving transistor is prevented, thereby enhancing picture quality. The light emitting display comprises: a plurality of light emitting devices formed adjacent to a region where data and scan lines cross each other; and a plurality of pixel circuits, each including a driving transistor for supplying current corresponding to a data signal to a respective one of the light emitting devices. The positions of the driving transistors are different from each other with respect to at least one of horizontal and vertical directions. With this configuration, a stripe pattern is prevented from appearing perpendicular to a scanning direction of a line beam emitted from an excimer laser during the fabrication method.

摘要： A method of manufacturing an active matrix substrate that enables increased productivity due to a reduction in the number of patterning processes and low generation of particles during the patterning processes. The method includes forming a patterned electrode on a substrate, and covering the first electrode with an insulating film. A mono-crystalline semiconductor layer is then formed on the insulating film by attaching a first layer formed on a surface of a semiconductor wafer to the insulating film, and peeling off a portion of the semiconductor wafer. The semiconductor layer is then patterned and doped, in part, by utilizing the patterned electrode as a photo mask for light illuminated from a lower side of the substrate. This results in part in mono-crystalline active layers for thin film transistors, which are then configured to form a pixel for an active matrix substrate.
