A connector comprises a first connector and a second connector to be connected with the first connector. The first connector includes a first housing, a holding portion, and a stopper. The second connector includes a second housing, a held portion, and an engagement portion. At the waiting position, the first connector and the second connector are movable between positions in a wall contact state, at which the leading end of the second connector is in contact with the wall defining the receiving space of the first connector, and positions in a stopped state, at which the stopper of the first connector and the engagement portion of the second connector are in contact with each other.

Connector, connector mounting board, illumination device, and display device

The display apparatus includes an optical sheet provided between a display panel and direct type light sources, and an inner chassis (support body)having a frame-shape which supports the back surface of peripheral edge parts of the display panel. A light shielding member is provided over an entire periphery of the display panel at the back side of the peripheral edge part thereof. An outer frame part of the light shielding member is sandwiched between the display panel and the inner chassis, and an inner frame part of the light shielding member is sandwiched between the display panel and the optical sheet. Light passing through the optical sheet is shielded by the light shielding member even when trying to be leaked to an outside from the polarizing plate, such that the light is not leaked due to being shielded by the light shielding member. Therefore, the light is prevented from entering the peripheral edge part of the display panel, and an occurrence of light leakage is prevented.

Display apparatus

A display apparatus, comprising: a light source emitting light; a display panel displaying an image on a front face of the display panel, and facing the light source; and a diffusion section arranged between the light source and the display panel, wherein the diffusion section includes a diffusion sheet-fixed to a circumferential portion of the display panel via a frame body, and facing the display panel with a distance between the diffusion sheet and the display panel, and an optical sheet arranged in a gap between the display panel and the diffusion sheet.

A light source device according to the present invention includes a light guide plate, a light source opposed to one end face of the light guide plate, a casing with one face being open, which houses the light guide plate and the light source and a frame member fitted onto an edge of the casing, the casing includes a contact part directly or indirectly being in contact with the one end face of the light guide plate at a side of the light source, and the frame member includes an elastic contact part being in contact with the other end face of the light guide plate while being elastic, at a side opposite to the light source.

Light source device and display apparatus

Provided is a display device comprising a liquid-crystal panel and an optical sheet member including multiple stacked optical sheets emitting light from a light source toward the liquid-crystal panel, which can alleviate unevenness in light even in the case where, for example, light with such unevenness is emitted from the optical sheet member due to warps or wrinkles generated in the optical sheet member caused by heat generated by the light source. A diffusion sheet is provided between a liquid-crystal panel and an optical sheet member with a gap from the optical sheet member. The light emitted through the optical sheet member is diffused by the diffusion sheet and gap, and then enters the liquid-crystal panel.

Display device

A light source unit, comprising: a light guide plate; a light source facing to a peripheral surface of the light guide plate; and a reflection part reflecting light emitted from one surface of the light guide plate, wherein the reflection part comprises: an elongated portion, which is positioned at an outside of an edge of the light guide plate, being elongated in a direction crossing the one surface; and a protrusion portion, which is located at a position of the elongated portion that is away from the one surface, protruding from the position to the one surface, wherein the one surface side of the light source is covered with the protrusion portion.
