A liquid crystal display comprising: a light guide plate guiding light; a light source (131 a, 132a) disposed on each of opposing sides of the light guide plate; a lower receptacle including: a bottom plate on which the light guide plate and the light sources (131 a, 132a) are disposed, a lower receptacle side wall (172a, 172b, 172c, 172d) extending in a direction substantially perpendicular to the bottom plate and from an edge of the bottom plate, and an upper plate (173,174) extended from the side wall (172a, 172b, 172c, 172d) and substantially parallel to the bottom plate, wherein each of the light sources (131 a, 132a) is surrounded by a portion of the bottom plate, the lower receptacle side wall (172a, 172b, 172c, 172d) and the upper plate (173,174), and the upper plate (173,174) does not overlap the light guide plate, in a plan view of the liquid crystal display; a reflection sheet (160; 1161; 2161) disposed overlapping the bottom plate, the side walls (172a, 172b, 172c, 172d) of the lower receptacle, and the upper plates (173, 174) of the lower receptacle; and flat-plate optical sheets disposed not overlapping with the upper plates (173,174) of the lower receptacle, in the plan view; characterized in that an intermediate receptacle is adapted to contact both the light guide plate and the optical sheets, and to engage with the lower receptacle; the intermediate receptacle further comprises a spacer (154a, 154b) projecting from the fixing members (153a, 153b) toward the bottom plate; and a boundary between the fixing member (153a, 153b) and the spacer (154a, 154b) defines intermediate receptacle projecting parts and intermediate receptacle recessed parts which are alternately disposed with each other along the first direction and correspond to the lower receptacle upper plate projecting parts (173a, 174a) and the lower receptacle recessed parts. a light guide plate guiding light; a light source (131 a, 132a) disposed on each of opposing sides of the light guide plate; a lower receptacle including: a bottom plate on which the light guide plate and the light sources (131 a, 132a) are disposed, a lower receptacle side wall (172a, 172b, 172c, 172d) extending in a direction substantially perpendicular to the bottom plate and from an edge of the bottom plate, and an upper plate (173,174) extended from the side wall (172a, 172b, 172c, 172d) and substantially parallel to the bottom plate, wherein each of the light sources (131 a, 132a) is surrounded by a portion of the bottom plate, the lower receptacle side wall (172a, 172b, 172c, 172d) and the upper plate (173,174), and the upper plate (173,174) does not overlap the light guide plate, in a plan view of the liquid crystal display; a reflection sheet (160; 1161; 2161) disposed overlapping the bottom plate, the side walls (172a, 172b, 172c, 172d) of the lower receptacle, and the upper plates (173, 174) of the lower receptacle; and flat-plate optical sheets disposed not overlapping with the upper plates (173,174) of the lower receptacle, in the plan view; characterized in that an intermediate receptacle is adapted to contact both the light guide plate and the optical sheets, and to engage with the lower receptacle; the intermediate receptacle further comprises a spacer (154a, 154b) projecting from the fixing members (153a, 153b) toward the bottom plate; and a boundary between the fixing member (153a, 153b) and the spacer (154a, 154b) defines intermediate receptacle projecting parts and intermediate receptacle recessed parts which are alternately disposed with each other along the first direction and correspond to the lower receptacle upper plate projecting parts (173a, 174a) and the lower receptacle recessed parts. a bottom plate on which the light guide plate and the light sources (131 a, 132a) are disposed, a lower receptacle side wall (172a, 172b, 172c, 172d) extending in a direction substantially perpendicular to the bottom plate and from an edge of the bottom plate, and an upper plate (173,174) extended from the side wall (172a, 172b, 172c, 172d) and substantially parallel to the bottom plate, wherein each of the light sources (131 a, 132a) is surrounded by a portion of the bottom plate, the lower receptacle side wall (172a, 172b, 172c, 172d) and the upper plate (173,174), and the upper plate (173,174) does not overlap the light guide plate, in a plan view of the liquid crystal display; a reflection sheet (160; 1161; 2161) disposed overlapping the bottom plate, the side walls (172a, 172b, 172c, 172d) of the lower receptacle, and the upper plates (173, 174) of the lower receptacle; and flat-plate optical sheets disposed not overlapping with the upper plates (173,174) of the lower receptacle, in the plan view; characterized in that an intermediate receptacle is adapted to contact both the light guide plate and the optical sheets, and to engage with the lower receptacle; the intermediate receptacle further comprises a spacer (154a, 154b) projecting from the fixing members (153a, 153b) toward the bottom plate;
