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.

摘要： A reflection type liquid crystal display device includes first and second gate lines, first and second data lines intersecting said first and second gate lines, an insulating layer covering said data lines, and a pixel electrode overlapping the first and second data lines in order to increase the aperture ratio. The overlapped area between the pixel electrode and the first data line and the areas between the pixel electrode and the second data line are substantially the same with each other. Each overlapped area covers substantially half of the length of the data line. Consequently, the reflective pixel electrodes cover the data lines substantially on the whole.

摘要： An electro-luminescence display (ELD) wherein a voltage supply line is separated into a plurality of lines to reduce the number of pixels connected to each line. In the ELD, a pixel array has a number of pixels, each of which includes an electro-luminescence device having a luminescent layer made from an-electro-luminescent material, an anode electrode and a cathode electrode serving as a common electrode. The pixel array is arranged in an active matrix type. A gate driving circuit and a data driving circuit are connected, via a number of scanning electrode wiring and a number of data electrode wiring, respectively, to the pixel array, for switching the pixels to selectively drive the pixels. First and second supply voltages are applied from an external circuit to the first and second supply terminals. First and second power supply lines couple the first and second voltage supply terminals with the pixel array. The pixels within the array are divided into blocks and pixels within a block are all connected to a supply line for that block. Accordingly, excessive current is not generated, which prevents head damage to the ELD and thus improves reliability.
