Abstract
An electro-optical device is capable of high quality images. An electro-optical device () includes a first capacitive element (), a second capacitive element (), and a third capacitive element (). The first capacitive element () includes a first conductive film (), a first part of a second conductive film (), and a first dielectric film (). The second capacitive element () includes a third conductive film (), a second part of a fourth conductive film (), and a second dielectric film (). The third capacitive element () includes the third conductive film (), a third part of the fourth conductive film (), and the second dielectric film (). Since a capacitive element that includes a large capacitance value is formed in a narrow region, even if the pixel becomes smaller as the definition is increased, it is possible to realize an excellent electro-optical device in which display defects are suppressed.
