A liquid crystal display device irradiates a light of a light source from a backside of a liquid crystal panel. A light-guiding plate provided under the liquid crystal panel guides the light of the light source to the liquid crystal panel by transmitting the light therethrough. An optical sheet is arranged between the liquid crystal panel and the light-guiding plate. A backlight housing accommodates the light-guiding plate and the optical sheet. The optical sheet has a protruding part extending outwardly from a periphery thereof. The backlight housing has an opening at a position corresponding to the protruding part.
