<P>PROBLEM TO BE SOLVED: To prevent variance of luminance depending on parasitic capacitance. <P>SOLUTION: An image display includes an organic EL device OLED that emits light via energization; a driving transistor Td that includes a gate (first terminal), a drain (second terminal) and a source, and that controls the organic EL device OLED according to a potential difference which is applied between the gate and the drain and is higher than a predetermined driving threshold; a transistor Tth for threshold voltage detection that detects a threshold voltage corresponding to the driving threshold between the gate and the drain of the driving transistor Td; and a variable capacitance Cc that is connected to the driving transistor Td. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
