Liquid crystal displaying element

Abstract

Abstract PURPOSE:To obtain the displaying element having the excellent time division driving characteristic and the satisfactory picture quality by setting the twisting angle of the helical structure of the liquid crystal molecule to 160-360 deg., and dislocating the constant angle in the liquid crystal orientating direction for the absorbing axis of the polarizing plate of the color polarization by one side provided upward and downward. CONSTITUTION:A nematic liquid crystal 17 sandwiched between upper lower electrode substrates 11 and 12 has the helical structure in the thickness direction, and a twisting angle alphaformed in the respective rubbing directions 6 and 7 of the substrates 11 and 12 is 180 deg.. Angles beta1 and betadelta2 formed by absorbing axes 8 nd 9 of upper and lower polarizing plates 15 and 16 to sandwich the substrate and the rubbing directions 6 and 7 are dislocated to the scope of 20 deg.-70 deg., one side polarizing plate is made into the color polarizing plate, and therefore, the transmissivity wavelength dependency due to the dissidence of the polarizing axis and the liquid crystal light axis of the incident light is corrected and the transmitting light is made into almost the achromatic color. The product of the thickness of the liquid crystal and the refraction factor anisotropy is 0.7-1.2mu, and the time division ability can be enlarged. Consequently, the time division driving characteristic is enhanced, the displaying background is made into almost the achromatic color and the high quality displaying can be executed.
