Patent ID: 8217920

Claim:
An apparatus, comprising: a display device comprising a data-holding circuit having a capacitance; a display portion having a plurality of pixel electrodes; a first carrier substrate on which the data-holding circuit and the display portion are formed; and a second carrier substrate that is disposed opposite to the first carrier substrate being placed above the display portion, an opposing substrate being absent above an area in which the data-holding circuit is disposed, wherein a provider of the capacitance comprises a sense amplifier circuit for amplifying and latching a magnitude of an electric potential between two nodes; the sense amplifier circuit has a first and second latch circuit; the display device has a transmission control portion being provided that allows or disallows signal transmission between one of the two nodes and at least one of the first and second latch circuits; and the output voltage amplitude of the first latch circuit is less than the output voltage amplitude of the second latch circuit; and an electroconductive layer disposed around a periphery of the display device, a distance between the data-holding circuit and the electroconductive layer around the periphery of the display device being more than 100 times greater than a thickness of a dielectric body which constitutes the capacitance of the data-holding circuit.
