摘要： There are disclosed an optical storage device for accessing an optical recording medium such as a phase change type of optical disk and an optical magnetic disk, and a liquid crystal device preferably applicable to such a optical storage device. The liquid crystal device has a structure that two liquid crystal layers, each of which has stripe-like shaped electrodes arranged in a direction perpendicularly intersecting one another, are superposed. This structure makes it possible to effectively correct an aberration caused by a change in a depth from a surface of an optical recording medium to a condensing point, for example, in cases of unevenness in thickness of a protective layer and a multi-layer recording.

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.
