Abstract:
1. An electro-optical device comprising: a backlight device including: a first panel arranged opposite to the first surface of the light guide plate, the first panel modulating light when light from the first surface passes therethrough, the first panel including an outer circumferential edge of an image display region; a second panel arranged opposite to the second surface of the light guide plate, the second panel modulating light when light from the second surface passes therethrough; one or more optical sheets arranged between the light guide plate and the second panel; a light emitting element mounting substrate including: wherein one of the optical sheets is stacked 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 the outer circumferential edge 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 the part of the light emitting element mounting substrate is located at the space and the light emitting surface of the light emitting element faces the side end surface of the light guide plate.
