Abstract
An additional circuit is formed on a glass substrate, and a passivation film is deposited thereon. After an insulation film is deposited on the passivation film, a contact hole is formed, and a signal line is deposited and connected to the additional circuit. After the signal line and the insulation film are patterned, an organic insulation film is formed, to thereby have a surface of an uneven configuration depending on a step formed by the signal line and the insulation film. A reflective electrode is formed on the organic insulation film, to thereby have a surface of an uneven configuration. This eliminates the need to perform a photolithography process step for the formation of the surface of the organic insulation film in the uneven configuration, thereby reducing manufacturing costs.
