Abstract:
1. A liquid crystal panel comprising: a first substrate comprising a plurality of thin film transistors, a plurality of pixel electrodes, a plurality of first photo spacers, and a first alignment film formed on the first photo spacers and the plurality of thin film transistors, each first photo spacer being formed on a corresponding thin film transistor and corresponding to a drain electrode of the corresponding thin film transistor, the drain electrodes of the thin film transistors being connected to the corresponding pixel electrodes, each thin film transistor and the corresponding, pixel electrode connected to the thin film transistor defining a substantially rectangular pixel unit, and each thin film transistor being located at a first corner of a corresponding pixel unit; a second substrate parallel to the first substrate, the second substrate comprising a light-shield film, a plurality of second photo spacers corresponding to source electrodes of the plurality of thin film transistors, and a second alignment film formed on the second photo spacers, the second photo spacers being disposed between the light-shield film and the second alignment film; and a liquid crystal layer sandwiched between the first substrate and the second substrate; wherein the thin film transistors and the first and second photo spacers are covered by the light-shield film and do not overlap the plurality of pixel electrodes, the first alignment film has a first alignment direction extending from a second corner to the first corner of the pixel unit, and defines a plurality of first alignment defect areas adjacent to the first photo spacers along the first alignment direction, the first corner and the second corner are two diagonally opposite corners of the pixel unit, the second alignment film has a second alignment direction being perpendicular to the first alignment direction, and defines a plurality of second alignment defect areas adjacent to the second photo spacers along the second alignment direction, and the first and second alignment defect areas are covered by the light-shield film.
