Abstract:
A method for manufacturing an electrooptical device including a first substrate, a pixel electrode arranged on the first substrate, and a thin-film transistor arranged on the first substrate and coupled to the pixel electrode, the method comprising:forming, on the surface of the first substrate, the thin-film transistor including a channel region, a gate insulator formed on the channel region, and a gate electrode on the gate insulator, with the gate electrode facing the channel region with the gate insulator disposed therebetween, and a drain electrode connected to a drain region of the thin-film transistor, the drain electrode formed of a conductive layer having a light shield property, formed over and covering the channel region. depositing at least one interlayer insulator covering the thin-film transistor subsequent to the formation of the thin-film transistor, forming, in the interlayer insulator, a side portion formation trench that extends along the side of the channel region of the thin-film transistor, and depositing a first light shield layer covering at least the channel region of the thin-film transistor, wherein the first light shield layer is also deposited in the side portion formation trench as a light shield side portion when the first light shield layer is formed.
