PURPOSE:To improve display quality by specifying the axes of light transmission to the azimuth angle of a specific range. CONSTITUTION:The azimuth angle phi in the polar coordinates in which the axes 12a, 12a of transmitted light of the direction to allow the transmission of the light of polarizing plates 11, 12 of a liquid crystal element 1 have the beginning line 3 in the horizontal direction on the display surfaces 1a, 11b is specified within the range of either 15 to 75 deg. or 105 to 165 deg.. The reading of the display surface is possible even from the outside of a vehicle on a driver seat side if the element is constituted in such a manner. |
