Abstract: A lighting device includes a light source, a chassis, a reflection sheet, a spacer, and a press member. The chassis includes a bottom plate disposed on a side opposite to a light output side with respect to the light source and houses the light source. The reflection sheet includes a bottom portion disposed along the bottom plate and a rising portion rising from the bottom portion toward the light output side and reflects light. The spacer is arranged between the bottom plate and the rising portion. The press member has a press surface pressing the rising portion from the light output side. The press member and the spacer have mounting structures with which the press member is mounted to the spacer by moving the press member in a direction along the rising portion and to hold the press member to the spacer.
