Abstract:
1. A display panel device, comprising: a pixel unit including a luminescent layer that defines a luminescent region having a long axis and a short axis; and a lens that is located above the pixel unit, covers the luminescent region, and transmits light emitted from the luminescent layer, wherein a height between a luminescent face of the luminescent region and an apex of the lens is uniform along a straight line in a long axis direction of the luminescent region, and in the lens, a cross-section of a light emitting side corresponding to a short axis direction of the luminescent region has a uniform shape in the long axis direction of the luminescent region in which the height is uniform, and at both end parts of the lens, each of (i) the cross-section of the light emitting side corresponding to the short axis direction of the luminescent region and (ii) a cross-section of the light emitting side corresponding to the long axis direction of the luminescent region has a shape of an elliptic arc having a predetermined curvature, and the lens deflects the light emitted from the luminescent layer in both of the short axis direction and the long axis direction of the luminescent region, wherein the display panel device satisfies h/w≦1, where w denotes a length of a bottom face of the lens that corresponds to the short axis direction of the luminescent region, and h denotes the height between the luminescent face of the luminescent region and the apex of the lens.
