摘要： To manufacture an active-matrix substrate, a metal film is formed on a glass substrate. The metal film has a first region and a second region, which lie between other regions of the metal film that will be gate lines and auxiliary capacitance lines. The first and second regions are removed in a process of making, in the metal film, through holes achieving ion doping. Thereafter, the metal film including the first and second regions is patterned, thereby forming gate lines and auxiliary capacitance lines. Hence, the first and second regions of the metal film are etched twice, without increasing the number of steps of manufacturing the active-matrix substrate. The probability of short-circuiting between any gate line and the adjacent auxiliary capacitance line is therefore low.

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 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 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.
