Structure of a pixel driving circuit for an electroluminescent display

摘要

An electroluminescent apparatus comprising:
a substrate;
a transistor formed above the substrate;
an inner layer insulation film overlapping the transistor and including a contact hole;
a pixel electrode formed on the inner layer insulation film and coupled to the transistor through the contact hole;
an opposite electrode opposed to the pixel electrode;
a luminescent element provided between the pixel electrode and the opposite electrode; and
a bank layer provided above the inner layer insulation film, the bank layer overlapping the contact hole and bordering the luminescent element.
