Abstract
An electro-optical device includes a scan line, a data line, a pixel circuit, and an enable line. The pixel circuit includes a memory circuit, a light emitting element, and a first transistor. The light emitting element changes brightness in response to an image signal held in the memory circuit. The first transistor controls light emission and non-light-emission of the light emitting element. A field for displaying a single image each includes a sub-field (SF) and a sub-field (SF). The sub-field (SF) and the sub-field (SF) include a non-display period during which the light emitting element does not emit light and a display period during which the light emitting element is allowed to emit light. A length of the display period in the sub-field (SF) is different from a length of the display period in the sub-field (SF).
