Chevron-type liquid crystal device having effective display and pattern display regions |
摘要 |
A liquid crystal display panel includes a pair of substrates having thereon scanning electrodes and data electrodes so as to form an electrode matrix, and a chiral smectic liquid crystal disposed between the scanning electrodes and data electrodes to form a plurality of smectic layers each including a plurality of liquid crystal molecules. The scanning electrodes and data electrodes are driven to define an effective display region and a frame-like fixed or semi-fixed pattern display region disposed outside the effective display region and extending along at least one side of the display panel. The smectic layers of the chiral smectic liquid crystal are aligned to extend in a direction which is non-parallel with the extension of the frame-like fixed or semi-fixed pattern display region so as to obviate the occurrence of cell thickness irregularity and liquid crystal voids.
