PURPOSE: A pico projector unit is provided to improve color uniformity projected to a dichroic filter and enable to reduce a size. CONSTITUTION: A pico projector unit comprises a first light source chip(101), a second light source chip(102), a dichroic filter unit(120), and a light equalizing unit. The first light source chip comprises a first light source projecting first light beams. The second light source ship comprises a second light source(102a) projecting second light beams and a third light source(102b) projecting third light beams. The dichroic filter unit is arranged in a progressive route of the first, second, and third light beams and composed of a first dichroic filter(121) and second dichroic filter(122). The light equalizing unit transmits lights projected from the dichroic filter toward a rear end part as uniform lights having a square shaped optical profile. |
