Abstract

PURPOSE: By utilizing the fact - that when a polarizing plate is irradiated by X-rays, the wave-length characteristics of its light transmission factor change - and by enhancing the light transmission factor in the visible light region with changed irradiating durations, the contrast of the display device at the brightly-lit place can be enhanced.
