LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE:To improve a visual angle range by forming the titled device so that the product of the anisotropic value of an refractive index of liquid crystal and a gap value between oppositely arranged electrodes is set to a prescribed value. CONSTITUTION:A liquid crystal panel A is obtained by filling a space between a pair of transparent conductive films 1 oppositely arranged with a prescribed interval (d) with liquid crystal 2 and arranging a glass plate 3 and a polarizing plate 4. The product DELTAn.d of the anisotropic value DELTAn of the refractive index of liquid crystal and the gap (d) between both the electrodes 1 is set up to 0.9mum<=DELTAn.d<=1.1mum. If it is defined that theta2 is a limit from which a fixed value or more crosstalk starts to be seen at non-selected voltage and theta1 is a limit enabled to observe display with a fixed value or more density at a selected voltage when the value of n.d is set up to said range, the visual angle range thetas= theta2-theta1 shows the widest value.
