To realize an electro-optic device that can display a high quality image having high resolution and multi-gradation with low power consumption, that operates more quickly, and that can get brighter display.SOLUTION: An electro-optic device 10 comprises: a scan line 42; a signal line 43; a pixel circuit 41 provided corresponding to a cross between the scan line 42 and the signal line 43; a first high potential line 47 supplying first potential; a low potential line 46 supplying second potential; and a second high potential line 49 supplying third potential. The pixel circuit 41 comprises: a light-emitting element 20; a storage circuit 60 arranged between the first high potential line 47 and the low potential line 46; a first transistor 31 whose gate is electrically connected to the storage circuit 60; and a second transistor 32 whose gate is electrically connected to the scan line 42. The second transistor 32 is arranged between the storage circuit 60 and the signal line 43, and an electric potential difference between the first potential and the second potential is smaller than an electric potential difference between the second potential and the third potential.SELECTED DRAWING: Figure 8 【課題】高解像度で多階調の高品位な画像を低消費電力で表示でき、より高速で動作しより明るい表示が得られる電気光学装置を実現すること。【解決手段】電気光学装置１０は、走査線４２と、信号線４３と、走査線４２と信号線４３との交差に対応して設けられた画素回路４１と、第１電位が供給される第１高電位線４７と、第２電位が供給される低電位線４６と、第３電位が供給される第２高電位線４９とを備え、画素回路４１は、発光素子２０と、第１高電位線４７と低電位線４６との間に配置された記憶回路６０と、ゲートが記憶回路６０に電気的に接続された第１トランジスター３１と、ゲートが走査線４２に電気的に接続された第２トランジスター３２とを含み、第２トランジスター３２は、記憶回路６０と信号線４３との間に配置され、第２電位に対する第１電位の電位差は、第２電位に対する第３電位の電位差よりも小さいことを特徴とする。【選択図】図８
