A display device includes a display housing and plural display-light-emitting devices. At least one of the plural display-light-emitting devices includes a light guide member, a holding member, and a light source. The light guide member includes a light incident portion, a light exit portion, and a reflecting portion. The light guide member causes light incident upon the light incident portion to be reflected by the reflecting portion so as to guide the light to the light exit portion. The holding member has an opening so as to house the light guide member, includes an elastically deformable holding piece, and holds the light guide member by using the holding piece. The light source is provided at a portion facing the light incident portion. The holding member has a cut that allows the holding piece to be elastically deformed.
