Abstract: In an embodiment, a display panel unit includes a reflective polarizing layer, a transparent layer, and a display panel. The polarizing layer transmits a first polarized component of light incident on an incident surface to an exit surface and reflects a second polarized component of the light. The transparent layer transmits the first and second polarized component of the light incident on a second surface to a first surface adhered to the incident surface and transmits the second polarized component reflected by the polarizing layer to be incident on the first surface to the second surface. The panel faces the exit surface, and selectively transmits the light exiting from the exit surface.

Abstract: A performance of an apparatus is improved. A display apparatus includes: a light guide panel; a light source unit including a plurality of light emitting diode elements arranged in an X direction at a position facing a side surface of the light guide panel; and a plurality of lenses arranged in the X direction between the light guide panel and the light source unit and adhered to each other while sandwiching an adhesive layer allowing visible light to penetrate therethrough. Each of the plurality of lenses includes a surface facing the light source unit, a surface opposite to this surface, and a side surface (lens side surface) crossing these surfaces and being adhered to the adhesive layer. The adhesive layer is arranged between the sides surfaces facing each other.
