半導体装置及び電子機器
Document Type and Number:
Japanese Patent JP5448271
Kind Code:
B2
Abstract:
To constitute a display panel only by transistors having the same conductivity type is difficult if a p-type transistor is adopted as a driving transistor. By constituting a circuit formed in the display panel by transistors having the same conductivity type, manufacturing process can be reduced, and cost reduction can be achieved. In the invention, an n-type transistor is used as a driving transistor for driving a light emitting element, and the driving transistor and the light emitting element constitute a source follower circuit.
