摘要:
A display of an electrochromic type, including an active matrix substrate on which a plurality of pixel electrodes corresponding to pixels are arranged in a matrix form; a counter substrate which is provided with a transparent electrode that is common with respect to a plurality of the pixel electrodes; and an electrochromic material which is sandwiched between the active matrix substrate and the counter substrate, and is colored in a boundary either between itself and the pixel electrode or between itself and the transparent electrode; wherein the pixel electrode other than an electrode-exposed part which contacts with the electrochromic material is covered with a transparent protective film; and the electrode-exposed part has a different area from the area of the part onto which a current generated between the transparent electrode and the pixel electrode concentrates, out of the transparent electrode.
