Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPS63202717
Kind Code:
A
Abstract:

PURPOSE: To permit correction of the pretilt angle of a liquid crystal which is fluctuated by a temp. fluctuation by constituting a titled device in such a manner that the polarization directions of polarizing plates can be adjusted by varying the installation condition of the polarizing plates in accordance with the fluctuation in the pretilt angle of the liquid crystal sealed into the device.

CONSTITUTION: An operator turns a driving gear 35 of the device in an arrow B direction by the fingertip to rotate a gear 31 in an arrow C direction when, for example, a temp. change arises in the liquid crystal 28 sealed in the device and the contrast of the display is deteriorated. The upper polarizing plate 29 is thereby moved in an arrow D direction with respect to the lower polarizing plate 30. The upper polarizing plate can be moved in the direction opposite from the arrow D direction with respect to the lower polarizing plate 30 when the driving gear 35 is turned in the direction opposite from the arrow B direction. The fluctuation in the molecular axis arrangement direction of the liquid crystal, i.e., pretilt angle, generated by the temp. fluctuation is easily corrected in the above-mentioned manner and, therefore, the display device having the good contrast is obtd.
