In each pixel of a display element, a memory circuit is made up of two complementary
inverters which are connected to each other in a loop manner, and stores whether
or not to light an Organic Emission Diode, according to a potential which is given
via a select circuit in a select period. An output end of one of the inverters
is directly connected to an anode of the Organic Light Emission Diode, and both
TFTs of the inverter drive the Organic Light Emission Diode. Thus, even though
dispersion in manufacturing occurs, it is possible to light/unlight the Organic
Light Emission Diode at the same luminance level. As a result, even though dispersion
occurs in characteristics of elements which make up a pixel, it is possible to
realize a memory-integrated display element which can light the optical modulation
element at the same luminance level.
