Abstract:
1. A display device comprising: a pixel array unit including a plurality of pixel circuits disposed in a matrix having a row direction and a column direction, at least one of said pixel circuits comprising a driving transistor configured to control a driving current, a storage capacitor configured to store a signal corresponding to a signal potential of an image signal supplied via an image signal line and a sampling transistor, and an electro-optic element configured to emit light in accordance with the driving current, the driving current being based on the signal stored in said storage-capacitor and being received through the driving transistor and a switching transistor; and a control unit having an output stage that includes a first buffer transistor and a second buffer transistor configured to output a pulse signal for driving said pixel array unit, wherein the first buffer transistor for outputting a first pulse signal to the sampling transistor and the second buffer transistor for outputting a second pulse signal to the switching transistor are arrayed in the column direction, wherein a gate electrode of the first buffer transistor and a gate electrode of the second buffer transistor are arranged along the row direction, wherein one of the first buffer transistor or the second buffer transistor comprises an analog switch having a transfer gate configuration wherein two switching transistors having a different polarity are combined, and the remaining one is configured as an inverter-type buffer where a p-type transistor and an n-type transistor are cascade-connected, and wherein the two switching transistors and one of the p-type transistor and the n-type transistor are disposed in the row direction.
