PURPOSE:To enhance electron injection efficiency, and to display informations with high precision by simple construction by a method wherein metal oxide finely divided particles are included in the electron injection layer of an information display system to erase pictures by applying a voltage of reverse polarity between the electron injection layer and a hole injection layer. CONSTITUTION:A hole injection layer 11 manufactured of a semiconductor is formed on a conductive surface on the surface of a glass plate 10 of flat panel structure, and then a semiconductor metal oxide layer 12 is formed. Structural defects 13 to accelerate formation of color centers are formed in high density according to high doping in the layer 12 thereof. Moreover, an electron injection layer 15 is formed on the opposite side of the layer 12 from the injection layer 11. Moreover, negative potential against the conductive layer on the glass plate 10 is biased to a metal layer 14 formed on the layer 15. Thereupon, metal oxide finely divided particles are included in the layer 15 to enhance injection efficiency of electrons 17 into the layer 12, and informations are displayed on the flat panel with high precision. |
