Abstract
An LCD device comprises a plurality of transparent pixel electrodes, a first substrate, a second substrate, a liquid crystal material, and a light shield device. The first substrate has a plurality of terminals electrically connected to the transparent pixel electrodes via a plurality of outgoing lines, and the terminals are gathered to define a plurality of terminal groups, thereby defining a plurality of outgoing line groups. The second substrate has opposing electrodes opposite to the transparent pixel electrodes. The liquid crystal material is sealed between the first and second substrates. The light shield device is adjacent to the outgoing line groups and the terminal groups and adjacent to the outgoing lines within the outgoing line groups and the terminals within the terminal groups, but not touching the outgoing lines and the terminals for preventing the light leakage on the edge of the liquid crystal display.
