Abstract:
A reflective type liquid crystal display device, comprising a liquid crystal sandwiched between first and second substrates, a transparent electrode and a reflective electrode for driving the liquid crystal formed on mutually opposed inside faces of the respective substrates, and a polarizing plate formed on an outside face of one of the first or second substrates, wherein:the liquid crystal has an optical axis in its initial align state controlled into directions of normal lines of the substrates; a vertical alignment layer which controls a direction of the optical axis in the initial align state of the liquid crystal is formed on the respective opposed inside faces of the two substrates; when a voltage for driving the liquid crystal is applied between the electrodes, the liquid crystal is tilted to have an azimuth of the optical axis on a plane component of the first or second substrate forming an angle of approximately 45 degrees with respect to a polarization axis direction of the polarizing plate; and an anisotropy of refractive index &Dgr;n of the liquid crystal and a distance d between the first and second electrodes satisfies the following equation: &Dgr;nÂ·d&lE;âˆ’0.4d+0.95.
