<P>PROBLEM TO BE SOLVED: To provide an image display device suppressing the voltage drop of a data line caused by connecting both ends of a memory. <P>SOLUTION: The image display device includes a plurality of pixel circuits, a power line, the data line supplying a data signal to each pixel circuit, and a current path control portion. Each pixel circuit includes a light emitting element, a drive transistor controlling a current passing through the light emitting element, the memory provided between the data line and a gate electrode of the drive transistor to store potential difference, and a data line connecting switch connecting one end of the memory on the gate electrode side of the drive transistor to the data line. Before the data line supplies the data signal to each pixel circuit, the data line connecting switch is turned on, and the current path control portion interrupts a current path from the power line to the one end of the memory included in the pixel circuit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
