Abstract
A black matrix 2 and a taking out electrode 3 are formed on a glass substrate 1, using a light-shielding conductive film made of a metal or the like. On this film, an insulating film 4 is formed. At the same time, a taking out electrode window 5 is formed on the portion of the insulating film 4 corresponding to the taking out electrode 3. Then, an electrode for forming a coloring matter layer (ITO electrode) 6 is formed on the insulating film 4. Then, the taking out electrode window 5 is filled with an ITO electrode material, to electrically connect the taking out electrode 3 and the ITO electrode 6. Then the outer electrode was connected to the taking out electrode 3. The electricity was turned on the outer electrode to form a coloring matter layer 8 on the ITO electrode 6.
