Abstract
PURPOSE:To obtain a picture indicator havng a high image resolution by optical write, by laminating in order a photoconductive layer wich mainly consists of amorphous silicon, a layer for helping the color formation of a turn-on color forming substance, a turn-on color forming layer, and also an opposed electrode, on a transparent electrode. CONSTITUTION:A transparent electrode 11 is formed on a transparent glass plate 10, on which a photoconductive layer 12 mainly consisting of amorphous silicon that has been doped by 1-40atom% H is formed. Subsequently, a Cr2O3 layer 13 is formed, on which a layer of 1 layer or more for helping the color formation of a turn-on color forming substance (amorphous WO3, etc.) such as a mixing vapor- deposited layer 14 of Cr2O3 and V2O5, or Cr2O3 and SiO2, etc. is formed. After that, a turn-on color forming substance layer (amorphous WO3) 15 is formed on the layer 14, and furthermore, on the layer 15, an opposed electrode 16 is provided by means of vapor-deposition of gold, etc. A picture is exposed from the side of the transparent electrode 11, on a picture indicator obtained in this way, and negative voltage is applied to the electrode 16. Since the layers 13, 14 are provided, a current flowing in the layer 16 after the picture hasd been exposed decreases swiftly, the current still flows after an image of the layer 15 has been exposed, and a clear picture is obtained without causing deterioration of an image resolution.
