摘要： A light-emitting device used in a liquid crystal display device is provided with a planar illuminator that focuses emitted light on a predetermined light focus point, and an optical deflector that two dimensionally deflects the light from the planar illuminator. The planar illuminator switches an emission direction of the light to enable alternate switching between a first light focus state in which the predetermined light focus point is the position of a right eye of a viewer and a second light focus state in which the predetermined light focus point is the position of a left eye of the viewer. The optical deflector can modulate each of the predetermined light focus point in the first light focus state and the predetermined light focus point in the second light focus state according to movement of the viewer.

摘要： A light-emitting device includes a light-emitting element 110; and a lens section 132 covering over the light-emitting element 110. The lens section 132 includes an entrance surface S1 on which light from the light-emitting element 110 is incident; an exit surface S2 from which the light incident on the entrance surface S1 is emitted; and an optical axis L extending so as to penetrate the entrance surface S1 and the exit surface S2. A concave section 132a is formed in an area of the exit surface S2, which contains the optical axis L, and two flat sections 132b are formed so as to face each other across the optical axis L. The exit surface S2 defines an upwardly-protruding curved surface formed between the two flat sections 132b, and the optical axis L is coincidence with a reference optical axis of the light-emitting element 110.

摘要： A method for manufacturing an optical element comprises a step of press molding an optical element material 6 disposed between an upper press head (7) and its paired lower press head (8), wherein in the upper press head (7) and/or the lower press head (8) is formed a groove-like component that forms a non-cylindrical face or a cylindrical face as an optically effective component in the optical element material (6). This makes it possible to obtain an optical element with stable face shape precision, boosts productivity, and is also advantageous in terms of cost.
