Abstract: A pixel is formed by sealing an insulating liquid and floating particles in an area defined by a first substrate, a second substrate and partitions. The width of the partition has to be reduced in order to improve the pixel brightness by enlarging a flat electrode. In this case, the height of the partition has to be reduced for retaining the mechanical strength. If the height of the partition is reduced, an area of the partition electrode becomes small, thus failing to retain the memory effect. The planar surface of the partition is then formed into a zigzag shape so as to increase the area of the partition electrode.

Abstract: In a liquid crystal display device disposed with reflective regions and transmissive regions, two organic insulating films are formed on a connection terminal portion and radial non-uniformities are prevented from occurring when applying the upper organic insulating film. Pixel portions including transmissive regions and reflective regions are formed, and a second organic insulating film is formed between a metal layer that forms reflective electrodes and a transparent conductive film that forms pixel electrodes to planarize concavo-convexities in the reflective electrodes. In contact holes of a connection terminal portion, the inclination of a first organic resin film is made smooth to control the occurrence of radial non-uniformities occurring in the second organic insulating film.

Abstract: The present invention prevents the diffusion of an aluminum element into a polysilicon layer in a heating step when an aluminum-based conductive layer is used in a source/drain electrode which is in contact with low-temperature polysilicon whereby the occurrence of defective display can be obviated. An aluminum-based conductive layer is used in a source/drain electrode and a barrier layer made of molybdenum or a molybdenum alloy layer is formed between the aluminum-based conductive layer and a polysilicon layer. Further, a molybdenum oxide nitride film formed by the rapid heat treatment (rapid heat annealing) in a nitrogen atmosphere is formed over a surface of the molybdenum or the molybdenum alloy which constitutes the barrier layer.

Abstract: A liquid crystal display unit is used that has data lines made of a molybdenum-alloyed film having a chromium content from 2 wt. % or more, but up to 5 wt. %, or a molybdenum-alloyed film lamination (Mo—Cr) consisting of a first electroconductive film and a second electroconductive film, with the first electroconductive film having a chromium content from 2 wt. % or more, but up to 5 wt. % and the second electroconductive film being provided above the first electroconductive film and containing less chromium than the first electroconductive film does. The use of the data lines composed of these materials enables the following requirements to be satisfied: high dry-etching resistance, low resistance, low ACF contact resistance, low side etching rates, forward tapered wiring cross-sectional shape, and up to two lamination layers.
