Abstract
A picture generation apparatus includes: a light source substrate on which a light source is mounted; an optical member through which light emitted from the light source is transmitted; a display device configured to form, by the light transmitted through the optical member, light for generating a predetermined picture; a heat sink configured to dissipate heat generated from the light source substrate; and a lens holder configured to hold the optical member. The lens holder includes first engagement portions, and the heat sink includes second engagement portions. Each of the first engagement portions and a respective one of the second engagement portions are fixed to each other, so that the light source substrate is positioned and fixed in a state of being interposed between the lens holder and the heat sink.
