ABSTRACT:
An image display apparatus can be arranged so that a picture element capacity obtains a value provides display data retention of less than 99% by writing same data to a picture element a plurality of times during 1 frame period. This makes it possible to disuse the auxiliary capacity and to improve an aperture ratio. Moreover, with the present invention, an MOS transistor arranged in each picture element as a switching element for driving the picture element, a scan signal line driving circuit and a data signal line driving circuit for transmitting a driving signal based upon display data to the MOS transistor through a data signal line and a scan signal line, and a first frame memory and a second frame memory provided outside the picture element for storing display data to be outputted to a data signal line driving circuit for 1 frame are formed on one substrate. As a result, it is possible to improve package efficiency and lower cost by using a driver monolithic technique.
