Abstract
A display apparatus in which light outputted from an LED array arranged in a column is reflected by a vibrating mirror such that a two-dimensional image is obtained, comprising: a half mirror which reflects light having a wavelength identical with a light emitting wavelength of the LED array and transmits therethrough visible light having other wavelengths than the light emitting wavelength; the half mirror being so disposed as to not only transmit therethrough the visible light from outside but also reflect the light proceeding from the LED array via the vibrating mirror such that the two-dimensional image has an outer scene as its background.
