Patent ID: 7247357

Claim:
An image display device comprising a display section comprised of a plurality of pixels; and a control section which controls said display section, wherein said image display device includes a nonvolatile phase-change type memory device having a memory for image display which is comprised of phase-change device elements and TFTs each having only a drain electrode connected to a corresponding one of the phase-change device elements, and said nonvolatile phase-change type memory device is comprised of at least one variable-resistance memory element and at least one TFT, wherein said at least one variable-resistance memory element is comprised of a chalcogenide material containing at least one element of Te, Se and S, and wherein a resistance of said at least one TFT in a conducting state thereof is in a range of from 10 kΩ to 500 kΩ and a resistance of said at least one variable-resistance memory element in a high-resistance state thereof is 1000 kΩ or more.
