Liquid crystal display device and method for manufacturing same
Abstract:
The present invention provides a liquid crystal display device and a method for manufacturing the same that can improve aperture ratio of pixels while securing necessary storage capacitance using a simple configuration even if there is progress in high resolution of pixels. The liquid crystal display device according to the present invention is provided with a plurality of pixels. A thin film transistor array substrate includes gate lines and source lines arranged in a grid pattern on a principal surface of a supporting substrate, transparent pixel electrodes, and thin film transistors. Also, the thin film transistor array substrate includes a gate insulator, a passivation layer, a transparent conductive film, a first insulation layer, and transparent pixel electrodes stacked in order from a supporting substrate side. The transparent pixel electrodes are electrically connected with drain electrodes of the thin film transistors through contact holes formed in the first insulation layer. When a substrate surface is viewed in a direction of a normal to the substrate surface, the transparent conductive film does not overlap regions in which the transparent pixel electrodes and the drain electrodes are electrically connected with each other.
