<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display element displaying both white and black images and a colored image using a color polarizing plate. <P>SOLUTION: The liquid crystal display element is provided with: a liquid crystal layer 3 sealed in a clearance between a pair of substrates 1 and 2 and having liquid crystal molecules twisted at a predetermined twist angle between the pair of substrates 1 and 2; a plurality of electrodes 6 and 7 which are provided respectively on inner faces of the pair of substrates 1 and 2 facing the liquid crystal layer 3, and receive a voltage for controlling an alignment state of the liquid crystal molecules; a normal polarizing plate 9 arranged on an outer face of the observation-side substrate 1 and showing a polarizing action to light at all the wavelengths of a visible light band; a color polarizing plate 10 arranged on an outer face of the opposite-side substrate 2 and showing a polarizing action to light at wavelengths other than a specific wavelength of the visible light band; and a reflecting plate 11 arranged on a face opposite to the face facing the opposite-side substrate 2 of the color polarizing plate 10 and reflecting light incident from an observation side to the observation side. <P>COPYRIGHT: (C)2010,JPO&INPIT |
