摘要： A liquid crystal display panel is arranged such that a reflection member overlaps a light-shielding wiring pattern such that apertures are left unmasked. This prevents light use efficiency from being decreased due to a light-shielding wiring pattern having memory wiring layers. An array substrate includes a transparent electrode which applies a field to a liquid crystal layer, a light-shielding wiring pattern having one or more apertures which allow transmission of light incident on the liquid crystal layer from the reverse side of the array substrate, and a reflection member which reflects incident light applied from a counter substrate side through the liquid crystal layer.

摘要： A reflector has protuberances and recesses in each pixel region. The distances between the respective peaks of each two adjacent protuberances in the pixel region are distributed in the range from 5 μm to 15 μm. The incidence of peak distances within the range of ±0.5 μm from the most frequent peak distance ranges from 40% to 80%, and the area of regular reflection surfaces of the reflector tilted at angles of 4.5° or less to the principal surface of a substrate in the pixel region accounts for 35% or less of the area of the pixel region.

摘要： A liquid crystal display device includes a driving voltage supply line connected to a transfer pad through a contact hole. The contact hole is corroded under the open air in a prior art liquid crystal display device. According to the present invention, however, the contact hole is provided in an air tight place ranging from an edge portion of a display area through a sealing material, e.g., underneath the sealing material. With this structure the contact hole is not exposed to the open air so that its resistance to corrosion is significantly improved.

摘要： A liquid crystal display device has an array substrate and an opposite substrate arranged opposite to each other through a plurality of columnar spacers with a liquid crystal layer sandwiched therebetween. A plurality of wiring lines and coloring layers are provided over the array electrode. A frame pattern is formed on the array substrate at the outer side of the display area to prevent a light leakage at the outer peripheral edge of the display area. The frame pattern is so provided as to have a gap relative to the outermost peripheral side columnar spacers. At a gap between the frame pattern and the outermost peripheral side columnar spacers, a wiring line is provided with its portion formed in an overlapping relation to the frame pattern, thus blocking light.
