Abstract
A display apparatus includes: a display body that contains a phosphor; a light source that outputs an excitation light to excite the phosphor; a first lens and a second lens that focus the excitation light on a focal position inside the display body; a first drive mechanism that drives the first lens to vary the focal position; and a second drive mechanism that drives the second lens to reduce aberration that varies with a change in the focal position.
