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.

The present invention provides a thin film transistor, wherein the semiconductor channel region is patterned. Gate electrodes 102, gate insulating film 103, source electrodes 104, and drain electrodes 105 are formed on a glass substrate 101. A patterned insulating film is formed thereon, and a part of the film in the region 110 on the gate electrode is removed. An organic semiconductor film is formed thereon by vapor deposition. The organic semiconductor film 107 in the region 110, where the patterned insulating film is removed, becomes a channel region, and is separated from the organic semiconductor film 108 on the patterned insulating film 106. Therefore, the organic semiconductor channel region is patterned to have the same size as the gate electrode. In accordance with the present invention, a thin film transistor, wherein the semiconductor region is patterned precisely, becomes available.

The present method prevents malfunctions in switching caused by a light leakage current in an active matrix type thin film transistor substrate for a liquid crystal display and prevents display failures, by selectively disposing a self assembled monolayer film in a gate electrode-projected region of the surface of an insulator film with high definition, and by selectively improving the orientation order of an organic semiconductor film only in the gate electrode-projected region without improving the order at an irradiated portion with light outside the gate electrode-projected region.

摘要:
A liquid crystal display unit in which a voltage is applied to a pixel electrode and a common signal electrode constituted by two upper and lower transparent conductive layers having insulation layers disposed therebetween so that a liquid crystal is driven to control display can improve any one or both of reduction of a writing time of the liquid crystal (reduction of a capacitance between the pixel electrode and the common signal electrode) and reduction of a driving voltage of the liquid crystal. An inter-layer insulation layer between the transparent electrodes formed of different layers is constituted by at least one or a laminated structure of a part of a gate insulation layer, a part of a surface protection layer of a thin film transistor and an applied-type insulation layer and insulation layers in an area which is positioned above the lower transparent electrode.

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.
