A display unit of the present disclosure includes: a light source section that outputs light; a light uniformization section including at least one uniformization optical member and having a light entrance surface through which the light outputted from the light source section enters and a light output surface through which light is outputted; a condenser lens for the light outputted from the light uniformization section to enter; and a reflective light valve to be illuminated by light outputted from the condenser lens. A light condensing position for return light that is reflected by the light valve and returns to the light output surface of the light uniformization section via the condenser lens is configured to be located off a light condensing position of the light uniformization section on a light output surface side for the light outputted from the light source section.
