Abstract: This display module includes a display cell, a board, a light guide plate formed with a first engaging portion, and a holding member formed with a second engaging portion coming into contact with the first engaging portion to engage with the first engaging portion. At least either the first engaging portion or the second engaging portion is formed in a shape allowing the light guide plate to move in a direction orthogonal to the board in response to expansion or contraction of the light guide plate when the light guide plate expands or contracts.

Abstract: A display device includes a display component, a light source, a light guide plate, a spacer member, and a biasing member. The display component displays images. The light source emits light. The light guide plate guides the light emitted from the light source to the display component. The light guide plate has a light incident face on which the light emitted from the light source is directly incident. The spacer member is disposed in a region other than where the light guide plate and the light source are opposite each other such that the spacer member maintains a specific spacing between the light source and the light incident face of the light guide plate. The biasing member is arranged to bias one of the light source and the light guide plate towards the other of the light source and the light guide plate.

Abstract: A display device includes a display device body, a display portion arranged on the front side, a light source, a light source substrate, a light guide plate having a light incident surface, and a heat sink arranged to be opposed to the light incident surface of the light guide plate between the light guide plate and the light source substrate, including a light source arrangement hole configured to arrange the light source and a spacer portion arranged to be opposed to the light incident surface of the light guide plate between the light guide plate and the light source substrate and keeping an interval between the light incident surface of the light guide plate and the light source at a prescribed interval.

Abstract: This display device includes a display device body, a display portion arranged on the front side of the display device body, configured to display an image, a light source supplying light to the display portion, a first light guide plate arranged to be opposed to the light source, having a light incident surface including a side surface on which light emitted from the light source is incident and a light emitting surface provided on a side surface opposite to the light incident surface to emit the light incident from the light incident surface, a second light guide plate arranged to overlap with the first light guide plate, guiding the light emitted from the light emitting surface of the first light guide plate to the display portion, and a first reflective member arranged between the first light guide plate and the second light guide plate.

Abstract: This display module includes a display cell, a light source, a light guide plate, and a reflective sheet arranged on a side opposite to the display cell with respect to the light guide plate. A projecting portion protruding toward the light guide plate and coming into contact with the light guide plate is formed on a surface of the reflective sheet closer to the light guide plate.
