Claim Text:
1. A display device, comprising: a light source; a display panel that performs display using light from the light source; a light guide plate disposed behind the display panel to guide light from the light source towards the display panel, said light guide plate having a light-emitting surface on one surface thereof and having a light-receiving face on at least one side face thereof, said light-emitting surface facing a side of the display panel opposite to a display surface side thereof, said light-receiving face facing the light source; a chassis having at least a bottom plate, said chassis being disposed behind the light guide plate; a frame disposed on the display surface side of the display panel, said frame and the chassis housing therebetween the display panel, the light source, and the light guide plate; a light source substrate having the light source disposed on a front surface thereof that faces and is in parallel to the light-receiving face of the light guide plate; a substrate holding member that can slide in a direction perpendicular to the light-receiving face relative to the bottom plate of the chassis, the substrate holding member including at least a plate-shaped portion holding a rear surface of the light source substrate; a side wall facing the light-receiving face across the plate-shaped portion of the substrate holding member, said side wall extending from either the chassis or the frame and having a penetrating hole that penetrates the side wall in a thickness direction thereof; and a pillar-shaped member with one end thereof penetrating the penetrating hole engaging the plate-shaped portion of the substrate holding member so that the substrate holding member can be moved towards the light-receiving face by moving another end of the pillar-shaped member towards said side wall, wherein the frame is constituted of a panel pressing portion that presses the display panel from the display surface side, and a side wall portion that protrudes from a periphery of the panel pressing portion towards the chassis, wherein either the light guide plate or the side wall portion has a protrusion protruding towards another of the light guide plate or the side wall portion, a recess being provided at a location facing this protrusion and having an opening that corresponds to said protrusion, said recess being able to engage said protrusion, wherein a gap is provided between the protrusion and the recess, and wherein a plate spring that is elastically deformable is disposed in said gap in a direction perpendicular to the light-receiving face of the light guide plate.
