Abstract

PURPOSE:To increase the contrast, response speed, and display performance like lige, by providing the filter having maximum light emission at the short wave visual light region and absorbing the ultraviolet ray at the optical path of the display device using azozy compound system liquid crystal. CONSTITUTION:The mixture 5 with one or mixture of azoxy compound indicated in equation, or the mixture 5 of azoxy compound and other liquid crystal compound, is sealed between the electrode substrate 2 providing the transparent electrode 1 and the reflection substrate 4 providing the reflection film 4 evaporating Al, by means of the sealing member 7. At the upper part of the substrate 2 of this cell, polyvinyl system film filter 6 including the fluorescent dye such as 1,6-diphenyl- 1,3,5-hexatrien absorbing ultraviolet ray and having the maximum illumination at 365nm is provided. Thus, the azoxy compound absorbing the ultraviolet rays which is seen yellow can be avoided and the lost crystality due to the azoxy radical without O due to ultraviolet rays and due to cistransfer, can be prevented.
