ABSTRACT:
A display device of the present invention is provided with (a) electro-optic elements respectively composed of an n-type TFT and an organic EL element, which are arranged in a matrix, each of the electro-optic elements being arranged in a vicinity of an intersection of a data line and a gate line, (b) a condenser for holding a potential so as to drive and display the electro-optic element, (c) a buffer circuit for outputting a potential supplied from the condenser, (d) a p-type TFT and an n-type TFT provided in series with the condenser, and (e) an n-type TFT provided between the data line and the p-type and n-type TFTs, wherein a plurality of the condensers are provided with respect to each of the electro-optic elements, and the plurality of condensers are connected to an output terminal of the buffer circuit. This reduces the number of TFTs required per 1 bit of memory element and reduces a scale of a driver circuit arranged around a display screen.
