摘要： A guest-host type liquid crystal display device not requiring the use of external polarizers, comprises: two guest-host type liquid crystal cells which are superimposed one upon the other and which are constructed in a manner that the liquid crystal molecules contained in the respective cells and located close to the boundary between the two cells are aligned in a direction parallel to the plane of the boundary, but that the direction of alignment of the molecules in one cell is perpendicular to that in the other cell when a voltage is applied, or alternatively when no voltage is applied. In case the perpendicular state is realized when a voltage is applied, the molecules are caused to be rearranged in a direction normal to the substrate by the removal of the applied voltage, whereas in case said state is realized when no voltage is applied, such rearrangement can be achieved by the application of a voltage. The liquid crystal material to be used in the cells is selected from nematic liquid crystal material having a positive dielectric anisotropy and a material having a negative dielectric anisotropy. The device may contain at least one additional cell which is superimposed upon the two cells.

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.
