摘要： PROBLEM TO BE SOLVED: To achieve microfabrication of semiconductor chips used in a drive circuit and reduce its cost, by using each element isolation film for isolating active regions from each other.
SOLUTION: In a method of manufacturing a display device, the semiconductor chip is isolated into a low breakdown voltage region and a high breakdown voltage region; and both the low breakdown voltage region and the high breakdown voltage region have element isolation films, each of which comprises an oxide film and have their respective active regions two of which are isolated from each other by the element isolation film. More specifically, this manufacturing method has a step for so oxidizing selectively the semiconductor substrate of the semiconductor chip as to form in the principal surfaces of both the low breakdown voltage region, and the high breakdown voltage region the oxide films of the semiconductor chip by each of which the active regions are isolated from each other; a step for forming thereafter each silicon film on each oxide film; a step for so oxidizing the semiconductor substrate as to form gate oxide films on the active regions of both the low breakdown voltage region and the high breakdown voltage region, and as to form element separating films of the low breakdown voltage region and the high breakdown voltage region; a step for so etching the low breakdown voltage region as to remove the gate oxide films present on the low breakdown voltage region; and a step for so oxidizing the principal surface of the low breakdown voltage region as to form each gate oxide film on each active region of the low breakdown voltage region.

摘要： PROBLEM TO BE SOLVED: To reduce a thickness of a liquid crystal display, and to prevent the generation of cracks, in a miniaturized liquid crystal display.
SOLUTION: A portion of a TFT substrate 10 to which a lower polarizer 15 is adhered has a thin thickness, and the periphery of the TFT substrate including a terminal 40 has a thick thickness. A portion of a counter substrate 20 to which an upper polarizer 25 is adhered has a thin thickness, and the periphery of the counter substrate except for one side has a thick thickness in a U shape. Accordingly, in adhering the upper polarizer 25 to the counter substrate 20, a foreign material is hardly entangled. By applying chemical polishing to edges of the TFT substrate 10 and edges of the counter substrate 20, the edges 13 are rounded, whereby a probability of the generation of cracks caused by an impact or the like from the outside can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display wherein contrast of display is enhanced. SOLUTION: In the liquid crystal display wherein a reflection film is formed in a pixel region on the liquid crystal side surface on one substrate of respective substrates disposed opposite to each other via a liquid crystal and light from the other substrate side is made incident in the reflection film and then reflected by the reflection film to the other substrate side, formation of the reflection film is avoided in the vicinity of a projecting part formed in the pixel region. Thereby, contrast of display is further realized. COPYRIGHT: (C)2004,JPO
