Abstract: A liquid crystal display device 10 includes: a transparent substrate 11; a plurality of signal lines 17 and scan lines 16 arranged on the transparent substrate 11 in a matrix; a plurality of auxiliary capacitor lines 18 provided between the scan lines 16 so as to be in parallel with the scan lines 16; thin film transistors (TFTs) each provided in a vicinity of an intersection of the signal lines 17 and scan lines 16; and pixel electrodes 20 arranged in respective positions defined by the signal lines 17 and the scan lines 16 and each electrically connected to a drain electrode D of the thin film transistor (TFT); in which the thin film transistor (TFT)'s gate electrode G and the scan line 16 are covered by a gate insulating film formed by an insulating film (a first layer) 25 and an insulating layer (a second layer) 26, and the drain electrode D of the thin film transistor (TFT) extends to overlie an auxiliary capacitor electrode 18a, with the insulating layer (the second layer) 26 interposed between the drai

Abstract: A liquid crystal display device having a liquid crystal display panel, where a liquid crystal layer is inserted as to be sandwiched between a pair of substrates, and which is provided with polarizers on opposite sides of the liquid crystal layer with the substrates residing between the polarizers, in which a light reflecting metal layer is formed on the inner surface of the substrate on a display surface, and an ?/4 retardation film is arranged between the substrate and the polarizer to serve as light reflection preventing means for the purpose of preventing the light reflected by the metal layer from outputting from the polarizer toward the display surface even if outside light is reflected by the metal layer. According to the present invention, an inexpensive liquid crystal display device is thereby obtained, where the diminution of contrast in the display due to the reflection of outside light by a black matrix is reduced.
