Abstract: The present invention reduces brightness unevenness at the periphery of a non-display region in a display device that uses an edge-type backlight by means of a display device being provided with a liquid crystal panel, a light guide plate, which has the surface opposing the liquid crystal panel as the light emitting surface and one lateral surface other than the light emitting surface and the surface opposite the light emitting surface as the light incident surface, a light source unit, which opposes the light incident surface, and an opening that pierces the light guide plate from the light emitting surface to the surface opposite the light emitting surface, the configuration being such that the length (X) from the light incident surface to the center of the opening is at least ½ the length (L) from the light incident surface to the lateral surface opposite the light incident surface.

Abstract: An illumination device includes a light source that emits primary light and a wavelength conversion element that converts at least a portion of the primary light from the light source. The wavelength conversion element includes a phosphor layer having phosphors that absorb at least a portion of the primary light from the light source to emit secondary light, which is polarized, and polymers having birefringence. The phosphors have an anisotropic structure and are aligned generally along a first direction, and the polymers have polymer molecules that are aligned generally along the first direction. An angle formed by a direction of a transition dipole moment of each of the phosphors to a delayed phase axis of each of the polymer molecules with respect to the secondary light emitted from the phosphors towards the polymer molecules is 0° to 45°.
