摘要： A backlight system (30) includes a light emitting section (31) and an imaging optical system. The imaging optical system includes a first microlens array (MLA1) and a second microlens array (MLA2). The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed. The lenses (2A) are provided in one-to-one correspondence to the picture elements such that the lenses (2A) have their respective focal points at positions onto which beams of light having passed through the lenses (1A) are converged. The lenses (2A) thus deflect the beams of light which have passed through the lenses (1A) in a substantially vertical direction with respect to the display surface of the liquid crystal panel.

摘要： Conventional planar light source devices have a problem that increasing a utilization ratio of light results in a very narrow angle distribution of light. A planar light source device of the present invention has a light source (1), a light guide plate (2) for introducing light coming from the light source via a light-incident plane of the light guide plate and emits the light from almost all area of a light emission plane, and a light source side reflector (3) for reflecting the light coming from the light source and light which comes from the light source and is reflected by the light-incident plane of the light guide plate so that the reflected light is emitted to the light-incident plane of the light guide plate. The planar light source device further includes a lower side reflector (5) for introducing light emitted from the lower plane of the light guide plate into the light guide plate again, and an optical member (4) for changing a traveling direction of first light (10) which is introduced via the light-incident plane to pass through the light guide plate and is emitted from an upper plane of the light guide plate to a vertical upper direction. The lower side reflector is inclined by an angle of 5°-60° with respect to the lower plane of the light guide plate, and θ2=90°−θ1±10° is met where θ1 (°) represents a maximum angle between the upper plane and a direction in which the first light is emitted from the upper plane and θ2 (°) represents an apex angle of the optical member.

摘要： A liquid crystal panel (10) includes a liquid crystal layer formed with a p-type liquid crystal. The liquid crystal layer exhibits homogeneous orientation while no voltage is applied. Further, an electric field is applied to the liquid crystal layer in a direction same as dipole moments (μ) of liquid crystal molecules (3a) to which no voltage is applied. With these arrangements, it is possible to provide a liquid crystal panel and a liquid crystal display device, each of which adopts a new display mode that can achieve a wide viewing angle equivalent to an IPS mode, can achieve a high-speed response like an OCB mode or exceeding the OCB mode, and does not require an initial operation for orientation conversion to the bend orientation.
