ABSTRACT:
An electro-optical device includes a backlight device that has a light emitting element and a light guide plate in which light emitted from the light emitting element is incident on a side end surface thereof and is emitted from a first surface and a second surface thereof, a first panel that is arranged opposite to the first surface of the light guide plate to modulate light when light from the first surface passes therethrough, and a second panel that is arranged opposite to the second surface of the light guide plate to modulate light when light from the second surface passes therethrough. In the electro-optical device, one or more optical sheets are arranged between the light guide plate and the second panel, an optical sheet of the optical sheets is laminated on the second surface of the light guide plate such that an end edge of the optical sheet is positioned between the side end surface of the light guide plate and an outer circumferential edge of an image display region of the first panel to form a space having a predetermined width between the end edge of the optical sheet and the side end surface of the light guide plate, and a light emitting element mounting substrate on which the light emitting element is mounted is configured such that a part adjacent to a region on which the light emitting element is mounted is laminated on the space of the light guide plate and a light emitting axis of the light emitting element faces the side end surface of the light guide plate.
