Claim 8:
9. The display unit according to claim 1, wherein
the at least one uniformization optical member includes a microlens array that includes a plurality of microlenses,
the reflective light valve is to be inclined with respect to optical axes of the light uniformization section and the condenser lens, and
the inclination angle of the reflective light valve satisfies an expression below:

(½)arctan[(n+0.25)Pa/fc]<θp<(½)arctan[(n+0.75)Pa/fc]  (A)

where θp is the inclination angle of the reflective light valve, fc is a focal length of the condenser lens, Pa is a period of an array pitch of the microlens array, and n is an integer.
