摘要:
To simplify a manufacturing process of a transverse electric field mode liquid crystal display device by using a non-linear resistance element such as a TFD (Thin Film Diode) as a switching element. In a liquid crystal display device having a pair of substrates with liquid crystal interposed therebetween, one of the substrates consists of an electrode substrate. On the electrode substrate, there are provided a first group of electrodes, a second group of electrodes crossing the first group of electrodes with an insulating layer interposed therebetween, non-linear resistance elements, one end of each of the non-linear resistance elements being connected to the respective one of the second group of electrodes, and pixel electrodes opposing the first group of electrodes, each pixel electrode being connected to the other end of each of the non-linear resistance elements. Since the non-linear resistance elements have a so-called TFD (MIM) structure made of metal-insulating layer-metal, the manufacturing process is simple. Therefore, it is possible to manufacture the transverse electric field mode display device at low cost.
