A liquid crystal display device includes a first substrate; a second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a first polarizer provided on a surface of the first substrate which is on the opposite side to the liquid crystal layer; a second polarizer provided on a surface of the second substrate which is on the opposite side to the liquid crystal layer; a first phase compensation element provided between the first polarizer and the liquid crystal layer; and a second phase compensation element provided between the second polarizer and the liquid crystal layer. A plurality of pixel areas are provided for display. The first substrate includes at least one transmissive electrode, and the second substrate includes a reflective electrode region and a transmissive electrode region in correspondence with each of the plurality of pixel areas.

A display device, with a pair of substrates provided so as to face each other with a display medium interposed therebetween, includes, on a first substrate of the pair of substrates: switching elements disposed in a matrix; scanning lines and signal lines disposed so as to cross each other; and an interlayer insulating film provided so as to have the switching elements, the scanning lines and the signal lines on one surface thereof and pixel electrodes on the other surface thereof. Each of the pixel electrodes is electrically connected to a drain electrode of one of the switching elements via a contact hole which penetrates through the interlayer insulating film. The interlayer insulating film is made of an organic thin film having a high transparency and covers at least the switching elements, the scanning lines and the signal lines. Furthermore, the interlayer insulating film is provided so as to contact directly with the first substrate in a light-transmitting area which is not shaded at least by the switching elements, the scanning lines and the signal lines.

First and second gate insulating films, a semiconductor layer made of a-Si(i), and an etching stopper layer are formed to cover a gate electrode on a glass substrate. A drain electrode side contact layer and a source electrode side contact layer are made out of a-Si(n.sup.+) in such a manner to be cut off on the etching stopper layer. A disconnection preventing a-Si(n.sup.+) wire is formed below a source wire in its longitudinal direction, and atop of which a pixel electrode is formed. Since the disconnection preventing a-Si(n.sup.+) wire and source electrode side contact layer are spaced apart, static-induced characteristics deterioration of TFT and the point and line defects during the substrate fabrication sequence can be eliminated and the non-defective ratio of the display device can be improved drastically.
