<P>PROBLEM TO BE SOLVED: To provide a display apparatus in which unevenness of luminance is suppressed while also suppressing increase of power consumption. <P>SOLUTION: In a first pixel 12 which is one of a plurality of pixels arranged in a matrix state in the display apparatus 10, a first OLED (Organic Light Emitting Diode) 16 is a current driving type optical device. A first transistor 20 as a driving circuit drives the first OLED 16. An operational amplifier 14 amplifies a data signal for controlling the first transistor 20. A first sample hold circuit 28 holds an output of the operational amplifier 14. A voltage drop value on a signal line to which a driving current of the first OLED 16 flows is returned to an input of the operational amplifier 14 by negative feedback. While an output of the operational amplifiers 14 is held by the first sample hold circuit 28, operation of the operational amplifier 14 is stopped. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
