Abstract: An image display apparatus that includes a first light collecting-reflecting device (10, 11) which image light (L0) from an image forming apparatus enters, and a second light collecting-reflecting device (20, 21) which second light (L2), of the image light, having passed through the first light collecting-reflecting device enters. The first light collecting-reflecting device has transmission action and light collecting-reflecting action with respect to the image light. The first light collecting-reflecting device collects and reflects first light (L1), of the entering image light, toward a first conversion position in a viewer's eye (201). The second light collecting-reflecting device has at least the light collecting-reflecting action with respect to the image light. The second light collecting-reflecting device causes the second light to reenter the first light collecting-reflecting device and collects and reflects the second light toward a second conversion position. The second conversion position is different from the first conversion position in a plane orthogonal to an optical axis of the viewer's eye.

Abstract: An eyeball detection unit of the present disclosure includes an irradiator that projects substantially parallel illumination light toward a cornea of an eyeball, a detector that detects light intensity of reflected light from the cornea, and a detection controller that identifies a centroid offset in an angular direction of the light intensity of the reflected light from the cornea with respect to a reference optical axis on the basis of a detected value by the detector, and thereafter calculates a positional offset of a cornea position with respect to the reference optical axis.

Abstract: A light emitting device of the disclosure includes a first light source and a second light source; a light-guiding plate having a first main surface and a second main surface that face each other, a first end surface facing the first light source, and a second end surface facing the first end surface and the second light source; a prism sheet disposed to face the first main surface; and a reflection sheet disposed to face the second main surface. The light-guiding plate includes a plurality of first slope sections and a plurality of second slope sections both provided on one of the first main surface and the second main surface, in which the plurality of first slope sections are provided to allow the light-guiding plate to be thinner in a first direction that extends from the first end surface to the second end surface, and the plurality of second slope sections are provided to allow the light-guiding plate to be thicker in the first direction, and each provided alternately with each of the first slope sections in the first direction. A proportion of area occupied by the second slope sections increases in a predetermined range from the second end surface, as a distance from the second end surface increases.

Abstract: A light-emitting device of the present disclosure includes: a first light-guiding plate having a first light incidence surface and a first light emission enhancement surface provided with a first pattern; and a second light-guiding plate having a second light incidence surface and a second light emission enhancement surface provided with a second pattern. The first pattern is a pattern constituted by a plurality of first punctiform sections of which an arrangement pitch changes to cause density of the first punctiform sections to increase as a distance from the first light incidence surface increases, and the second pattern is a pattern constituted by a plurality of second punctiform sections of which an arrangement pitch changes to cause density of the second punctiform sections to increase as a distance from the second light incidence surface increases, and when viewed from the light emission direction, regions provided with the first pattern and the second pattern partially overlap, and directions in which densities of the first pattern and the second pattern increase are opposite to each other.
