Abstract
Each TFT for driving each of a plurality of pixels arranged in a matrix-like configuration is configured using a stagger-type polycrystalline-Si TFT. A gate electrode, which is composed of a high-heat-resistant material capable of resisting high temperature at the time of polycrystalline-Si film formation, is disposed at a lower layer as compared with the polycrystalline-Si layer that forms a channel of each TFT. A gate line, which is composed of a low-resistance material, is disposed at an upper layer as compared with the polycrystalline-Si layer. The gate electrode and the gate line are connected to each other via a through-hole bored in a gate insulation film. Respective configuration components of each organic electro-luminescent element are partially co-used at the time of the line formation, thereby suppressing an increase in the steps, processes, and configuration components.
