Abstract
A display device is provided with: a light guide plate having a light exit surface that emits light; a display panel; an optical sheet that is interposed between the light guide plate and the display panel and that comprises a plurality of rectangular unit sheets; and a holding frame section that surrounds the optical sheet and that holds the optical sheet. The holding frame section comprises a first side for holding the optical sheet, and a second side and a third side that intersect the first side at the two ends of the first side. A first protrusion and a second protrusion are provided to the two ends of the first side in the lengthwise direction thereof. A first unit sheet and a second unit sheet are each fixed by the first protrusion and the second protrusion. The second side faces an end side of the first unit sheet; and is in contact with all of said end side. The third side faces an end side of the second unit sheet and is in contact with all of said end side. As a result, light from the light exit surface of the light guide plate is prevented from leaking from a gap between the holding frame section and the optical sheet.
