Document Type and Number:
Japanese Patent JP2004264633
Kind Code:
A
Abstract:
To prevent display unevenness of an organic EL display panel by reducing variation of characteristics of a driving transistor among pixels.
A gate signal wire 10 supplying a gate signal Gn and a drain signal wire 11 supplying a display signal Dm cross each other. Driving TFTs 12, 13, 14, 15 of P channel type divided into four are disposed in the pixels. Divided anodes (positive electrodes) of the organic EL elements 16, 17, 18, 19 are connected to the respective drains of the driving TFTs 12, 13, 14, 15. Pixel selection TFT 21 is connected to the common gate of driving TFTs 12, 13, 14, 15.
