ABSTRACT:
A display apparatus is constituted by at least one display panel, such as a liquid crystal panel, so as to include a first display region and a second display region. At least one of the first and second display regions is provided with a memory characteristic so as to avoid the use of a special memorization means, such as a non-volatile memory or a temporary power supply. The first display region is used to effect an ordinary display, and the second display region is used to display system data. As a result, loss of data at the time of power supply interruption is prevented inexpensively, so as to recognize both stored display data and system data, such as error data and start up state data.
