A method for quantitative evaluation of the light-leakage caused by a spherical spacer in normally black mode LCDs was proposed. The normalized intensity of the light-leakage (L_<leak>) is defined as the increase of the transmittance by a single spacer in 1mm^2. The contrast ratio is estimated using the L_<leak>, can be improved by reducing the light-leakage. It is possible that the light-leakage intensity is reduced by aligning treatment on the spacer such as vertical aligning treatment. We have found that the light-leakage due to domain formation around spacers depended on spacers with aligning treatment. And, we found that a black spacer with vertical aligning treatment is more effective in the high contrast ratio than a spacer without aligning treatment.
