Abstract

A light transmitting container filled with gas is used to house a cold cathode fluorescent illumination apparatus (101) to reduce heat loss due to ambient temperature and to increase the luminous efficiency of the lamp (102). A display array comprising a plurality of illumination devices (102) arranged adjacent to one another can be used as a large screen display device which has high luminance, high efficiency, long lifetime, high contrast and excellent color.
