To make the device small in size.
The electrooptical device comprises a plurality of unit circuits which are provided corresponding to the crossing parts of a plurality of scanning lines and data lines in the operating region 12 of the substrate 10 and each of which comprises an electrooptical element 60, at least one peripheral circuit 14 which is formed at the surrounding of the operating region having an active element, and a sealing member 84 which has a fitting part 90 located so as to overlap with the peripheral circuit 14 and seals the electrooptical element 60. The peripheral circuit 14 is either one of a scanning line drive circuit for supplying a scan signal to the unit circuit through the plural scanning lines, an inspection circuit for inspecting the quality of the unit circuit, and a precharge circuit for outputting a precharge signal to the plural data lines.
