Abstract

PURPOSE: To establish the display unit having the electrode which is low in resistance and reduces the metallic brightness and its background, by forming the electrode coarse with a given heat treatment on the insulation substrate having flat surface.
CONSTITUTION: On the insulation substrate 3 of the sidplay unit using electrochemical phenomenon, no surface treatment is made but the glass flat for the surface is used. This substrate 3 is heated to 300°C under vacuum, and the mixture of Cr and Ni or Cr as the first layer is evaporated under vacuum and Au being the main electrode is evaporated under vacuum. Thus, the electrode 4 of Au in which no mirror reflection is represented and the crystal particles are enlarged, can be formed. Or, on the same substrate, Au,Pt or Cu is formed as the electrode metal with vacuum evaporation or sputtering method, and the crystal particles are enlarged with heat treatment at 200 to 500°C. Thus, the electrode having coarse surface and background not causing mirror reflection for various colors can be established by the electrode substance.
