Abstract
A liquid crystal display panel includes a first electrode substrate having a transparent electrode array, and a second electrode substrate having a second transparent electrode array which extends perpendicularly to the electrode array of the first substrate. The substrates overlap each other with separation walls interposed therebetween. The separation walls are formed in the spaces between individual transparent electrodes of one of the arrays and extend in parallel therewith. Liquid crystal, such as antiferroelectric liquid crystal, fills the space between the two electrode substrates. The liquid crystal near the separation walls is not properly oriented, and light leaks therethrough in the dark state of the liquid crystal. To prevent the light leakage, metal electrodes are formed along the separation walls so that the metal electrodes intercept the light passing through the liquid crystal near the separation walls. Thus, a high display contrast is realized.
