| 发明名称 | Light deflector, method of manufacturing light deflector, and liquid crystal display | ||
| 摘要 | A light deflector which deflects incident light and emits the deflected light, by changing a refractive index of a liquid crystal: a pair of ITO films; a plurality of prisms which are provided between the pair of transparent electrodes and are arranged on a facing surface of one of the pair of transparent electrodes, the facing surface facing a surface of the other one of the pair of transparent electrodes; two spacers arranged between the pair of transparent electrodes, and having, in a direction from one of the pair of transparent electrodes toward the other, widths which (i) are greater than widths of the prisms and (ii) are identical to each other; and a liquid crystal which is provided, within a space between the pair of transparent electrodes, in a portion other than a portion where the prisms and the two spacers exist. | ||

| 主权项 | 1. A light deflector which deflects incident light and emits the light which has been deflected, by changing a refractive index of a liquid crystal, the light deflector comprising: a pair of transparent electrodes which face each other; a plurality of prisms which are provided between the pair of transparent electrodes and are arranged on a facing surface of one of the pair of transparent electrodes, the facing surface facing a surface of the other one of the pair of transparent electrodes; two spacers arranged between the pair of transparent electrodes, and having, in a direction from one of the pair of transparent electrodes toward the other of the pair of transparent electrodes, widths which (i) are greater than widths of the prisms and (ii) are identical to each other; and a liquid crystal which is provided, within a space between the pair of transparent electrodes, in a portion other than a portion where the prisms and the two spacers exist, wherein each of the two spacers has: a portion in contact with the facing surface of one of the pair of transparent electrodes, and another portion in contact with the surface of the other one of the pair of transparent electrodes; and a shape similar to a shape of each of the prisms of the light deflector, such that each of the spacers can deflect incident light from a light source in a similar manner as the prisms. | ||
