发明名称 OPTICAL DEVICE
摘要 According to one embodiment, an optical device includes a first optical element and a second optical element. The first optical element has first and second surfaces. A first light emitted by a display is incident on the first surface. The first optical element includes transmissive portions and non-transmissive portions. Each of the transmissive portions extends in a first direction parallel to the first surface. The non-transmissive portions are respectively disposed in regions between the transmissive portions. A light transmittance of the non-transmissive portions is lower than that of the transmissive portions. A second light emitted from the second surface is incident on the second optical element, which emits a third light by condensing the second light. An optical axis of the third light is tilted with respect to an optical axis of the second light in a plane parallel to the first direction.
