Abstract: The present disclosure provides an image display that includes a light source unit, a display panel that displays image, and a light guide panel that guides light emitted from the light source unit to the display panel. The light guide panel has an incident surface facing the light source unit, an output surface facing the display panel, and a bottom surface facing the output surface on a side opposite to the display panel. The incident surface is a side surface of the light guide panel located between the output surface and the bottom surface. The incident surface has a concave portion in which a part of the incident surface is recessed from remaining portions when viewed from a direction perpendicular to a light guide direction of light in the incident surface and an emission direction of light in the output surface.
