摘要： In the present invention, a lower electrode is utilized as a photomask to form a liquid-repellent region having a generally same pattern shape as that of the lower electrode and a liquid-attracting region having a generally reversed pattern shape on an insulating film. A conductive ink is coated and calcined in the liquid-attracting region to form an upper electrode having a generally reversed pattern shape to the lower electrode in a self-aligned manner, eliminating the occurrence of misregistration even when a printing method is used. Consequently, semiconductor devices such as an active matrix thin film transistor substrate can be formed using a printing method.

摘要： An active matrix liquid crystal display device is provided for realizing a high uniformity of display luminance with lower power consumption, a higher contrast, and a wider viewing angle. In a common wire eliminated (common-less) IPS-type active matrix liquid crystal display device, an opposing electrode 107 is arranged above a signal wire 104 and a thin film transistor (TFT) through an insulating layer. The opposing electrode 107 and a scanning wire 101 shield the signal wire 104 or the TFT to prevent light from leaking from edge portions of the signal wire 104 as well as the TFT from malfunctioning due to a current generated by leaked light, thereby realizing the elimination of a black matrix (BM), a reduction in size of a black matrix, and planarized substrates, thus resulting in a higher aperture ratio and an improved uniformity of cell gap.

摘要： Each TFT for driving each of a plurality of pixels arranged in a matrix-like configuration is configured using a stagger-type polycrystalline-Si TFT. A gate electrode, which is composed of a high-heat-resistant material capable of resisting high temperature at the time of polycrystalline-Si film formation, is disposed at a lower layer as compared with the polycrystalline-Si layer that forms a channel of each TFT. A gate line, which is composed of a low-resistance material, is disposed at an upper layer as compared with the polycrystalline-Si layer. The gate electrode and the gate line are connected to each other via a through-hole bored in a gate insulation film. Respective configuration components of each organic electro-luminescent element are partially co-used at the time of the line formation, thereby suppressing an increase in the steps, processes, and configuration components.

摘要： There is provided a liquid crystal display device in which light leaks near spacers are prevented. The liquid crystal display device controls the optical transmissivity of a liquid crystal layer interposed between substrates disposed in opposition to each other, by means of an electric field generated in the layer-thickness direction of the liquid crystal layer, includes spacers formed on a liquid-crystal-side surface of one of the substrates, signal lines formed on a liquid-crystal-side surface of the other substrate, an insulating film formed to cover the signal lines, and electrodes formed on the upper surface of the insulating film, each of which serves as one electrode contributing to control of the optical transmissivity of the liquid crystal layer. Each of the spacers has a vertex surface disposed in opposition to any of the signal lines, and a portion of each of the electrodes is extended to the upper surface of a corresponding one of the signal lines and the extended portion is opposed to a part of the vertex surface of a spacer disposed in opposition to the corresponding one of the signal lines.
