Abstract

A display (A) includes a light source unit (1) for illuminating a planar region and a plurality of filter elements arranged in a matrix. Each of the filter elements transmits light emitted from the light source unit (1) and having a wavelength lying within a predetermined range. The light source unit (1) includes a plurality of semiconductor light emitting devices (2) arranged in a matrix on a common board. Each of the semiconductor light emitting devices (2) is adapted to emit white light including three wavelength peaks lying in a blue range, a green range and a red range, respectively.

Claims

1. A display comprising:

a light source unit for illuminating a planar region; and

a plurality of filter elements arranged in a matrix, each of the filter elements being adapted to transmit light that is emitted from the light source unit and has a wavelength lying within a predetermined range;

wherein the light source unit includes a plurality of semiconductor light emitting devices arranged in a matrix, each of the semiconductor light emitting devices being adapted to emit white light including three wavelength peaks lying in a blue range, a green range and a red range, respectively.

2. The display according to claim 1, further comprising a controller for performing individual brightness control of the lights emitted from the semiconductor light emitting devices, respectively.
