Abstract: A lighting device includes a light guide plate, a first light source, a second light source, and a case. The light guide plate includes plate surfaces and an outer peripheral surface. One of the plate surfaces is configured as a light exiting surface. Sections of the outer peripheral surface on opposite sides from each other relative to the center of the light exiting surface are configured as a first light entering surface and a second light entering surface, respectively. The first light source is disposed opposite the first light entering surface. The second light source is disposed opposite the second light entering surface. The case includes an annular wall portion surrounding an outer circumference of the light guide plate, the first light source, and the second light source. The annular wall portion includes light source non-disposing areas between the first light entering surface and the second light entering surface.

Abstract: The present invention provides a liquid crystal display device capable of achieving a high response speed. The liquid crystal display device includes: an upper substrate and a lower substrate; and a liquid crystal layer disposed between the upper and lower substrates, the upper substrate including an electrode, the lower substrate including paired electrodes, the liquid crystal layer containing liquid crystal molecules that are aligned in parallel with the main surfaces of the upper and lower substrates with no voltage applied, the liquid crystal display device being configured to provide one of white display and black display by utilizing an electric field generated between the paired electrodes of the lower substrate to rotate the liquid crystal molecules in one direction in a plane parallel to the main surfaces, and the other of white display and black display by utilizing an electric field generated by the respective electrodes of the upper and lower substrates to rotate the liquid crystal molecules in the opposite direction from the one direction in the plane parallel to the main surfaces.

Abstract: A backlight unite 12 includes LEDs 17, an optical member 16, a positioning portion 23, and a rotation restricting portion 24. The optical member 16 includes at least a curved end surface 16C having a curved shape in a plan view included in a periphery of the optical member 16. The positioning portion 26 includes a positioning hole 25 that opens through a thickness direction of the optical member 16 and a positioning protrusion 26 that is inserted in the positioning hole 25 and is in contact with an inner wall of the positioning hole 25. The rotation restricting portion 24 includes an optical member recess 27 that is a portion of the periphery of the optical member 16 recessed along a circumferential direction and a contact portion 28 that is in contact with the optical member recess 27.

Abstract: A backlight device 12 includes LEDs 17, an optical member 16 that applies optical effects to light from the LEDs 17 and has a through hole 23 that is through a thickness thereof, and a restricting member 26 having a communication hole 27 that is communicated with the through hole 23. The restricting member 26 is inserted in the through hole 23 to be in contact with an inner surface of the through hole 23 to restrict movement of the optical member 16 along a plate surface of the optical member 16.
