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 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 includes a thin film transistor (TFT) array substrate 10, a counter substrate 22 provided opposite to the TFT array substrate 10 and a liquid crystal layer 28 held between the TFT array and counter substrates 10 and 22. The TFT array substrate 10 has display and frame areas 31 and 32. There are pixel electrodes in the display area 31 which each have reflective and transparent portions 33 and 34 with convex and concave portions 29 and 30, respectively. Convex and concave portions 36 and 37 are also provided in the frame area 32 which are substantially the same in shape as convex and concave portions 29 and 30 in the display area 31. The surface of a photoresist coating film in the display area 31 shown by a dotted line 39 is substantially the same in configuration as that in the frame area 32 to make the column-like spacers 27 and 38 substantially the same in height. A cell gap between the TFT array and counter substrates 10 and 22 is made thereby substantially uniform.

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.

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.
