Abstract
A displaying device, which can reduce the power consumption, compared with a conventional displaying device in which the reduction of the power consumption is difficult because light is extracted from each of light emitting elements in time series, and also can prevent a displayed image from deteriorating caused by light entering from the outside or a light loss in a waveguide array, is provided. In the displaying device, a light emitting array controls each of light emitting elements. A waveguide array is formed by patterning a photosensitive resin formed on a supporting substrate having a light absorbing layer. A light extracting section extracts light at the same time form a predetermined selected region of the plural light emitting elements. The light extracting section also provides an antireflection layer on the surface facing to an observer. The extracting efficiency at the light extracting section is corrected corresponding to a light loss in the waveguide array. The light extracting section uses an optical material whose refractive index is changed by an external electric field.
