Abstract: A method for manufacturing an electrode substrate includes providing an insulating substrate and forming a first conductive layer on the insulating substrate. The first conductive layer has a narrowed wiring region and forms a first wiring pattern and a second wiring pattern. The narrowed wiring region defines a boundary region disposed between the first wiring pattern and the second wiring pattern. The method also includes forming a second conductive layer in electrical contact with the first conductive layer. The second conductive layer has a narrowed wiring region and forms a third wiring pattern and a fourth wiring pattern. The narrowed wiring region of the second conductive layer defines another boundary region disposed between the third wiring pattern and the second wiring pattern. The first and second conductive layers are formed such that the boundary regions of each of the first and second conductive layers do not overlap each other.

Abstract: A broad class of lyotropic liquid crystals of a non-surfactant nature, the so-called lyotropic chromonic liquid crystals (LCLCs), are alignable in bulk. LCLCs can be aligned in bulk as a uniform liquid crystalline monodomain within a closed cell. The method for bulk alignment of LCLCs is based on a unidirectional treatment of the aligning substrate such as a polymer layer. The feature of controlling the alignment of LCLCs enables one to create practical devices from them. For example, bulk alignment of LCLCs allows one to use them in detection and amplification of ligands.

Abstract: Parasitic capacity between Cs lines and source lines forming a pixel section is reduced, whereby characteristic resistant to crosstalk is achieved, aperture ratio is increased, and brightness of LCD is increased. The Cs lines are arranged on the source lines in such a manner as to cover the source lines, and pixel electrodes are arranged and formed on the Cs lines in such a manner as to partially overlap. By forming a structure in which the source lines, the Cs lines and the pixel electrodes are laminated in order, parasitic capacity between the Cs lines and the source lines forming a pixel section can be reduced, and crosstalk can be minimized. As a distance between the source lines and the pixel electrodes can be reduced from the viewpoint of a plan view, aperture ratio can be improved.
