PROBLEM TO BE SOLVED: To supply an electro-optical device performing high quality image display.SOLUTION: An electro-optical device includes: a scanning line drive circuit 38; a clock buffer circuit 203 for shaping a waveform of a clock signal CLY; first constant potential wiring VSS1 for supplying a first constant potential to the scanning line drive circuit 38; and second constant potential wiring VSS2 for supplying the first constant potential to the clock buffer circuit 203. The first constant potential wiring VSS1 and the second constant potential wiring VSS2 are electrically separated from each other. A potential of the first constant potential wiring VSS1 can be maintained within a normal range even when a potential of the second constant potential wiring VSS2 fluctuates due to behavior of the clock buffer circuit 203. More specifically, power source fluctuation noise due to the clock buffer circuit 203 on the scanning line drive circuit 38 can be suppressed. As a result of this, disturbance of a display image in a display area 34 can be suppressed, and high quality image display can be performed. |
