ABSTRACT:
A first amplifier circuit (132) included in a voltage generating circuit (114) includes a differential circuit formed of P-type TFT elements (P101, P102) and N-type TFT elements (N101, N102), a constant current circuit (150a,150b) and an N-type TFT element (N103). Constant current circuit (150a;150b) includes a P-type TFT element (P132a; P132b), a capacitor (C132a; C132b), switches (S104a-S106a; S104b-S106b) and a resistance element (R132a; R132b). Capacitor (C132a; C132b) holds a voltage on a node (204; 208) in a voltage setting operation, and thus when a current is being supplied to the diode-connected P-type TFT element (P132a; P132b).
