Patent ID: 7990369

Claim:
An image display apparatus comprising: an image display panel having a display element comprising a plurality of pixels arranged in a matrix at crossing points where a plurality of scanning electrode lines cross a plurality of signal electrode lines; a scanning electrode line selection circuit for selecting the scanning electrode lines of the image display panel; a signal electrode line drive circuit for driving the signal electrode line; storage means for storing display data for each pixel, said storage means comprising: memory element electrode, a phase change film in contact with the memory element electrode, and a resistor connected to each pixel; and a switching element for controlling the display state of the display element provided for the pixel, said switching element being a TFT including a gate electrode, wherein: the display data is stored in the pixel by way of the resistance value of the resistor, the storage means is a non-volatile memory, storage means is capable of rewriting the stored display data in a nonvolatile manner such that the stored display data does not change in the absence of power, the display state of the display element is controlled by controlling the switching element using a voltage that changes in accordance with the resistance value of the storage means, the switching element is turned on/off based on changes in the resistance value of the storage means, and the gate electrode and the memory element electrode have higher melting points than the phase change film.
