Patent ID: 8149182

Claim:
A dual-view liquid crystal display device, comprising: a display panel to display images; and a switching panel including first and second regions arranged alternately in a direction, the first and second regions controlled to represent a single image displayed on the display panel in a single-view mode and different images displayed on the display panel in a dual-view mode, wherein a line width of the first region is adjustable in accordance with a viewing angle of a user, wherein one of the first and second regions is controlled in a transmitting mode and the other is controlled in a blocking mode when in the dual-view mode, both the first and second regions of the switching panel being simultaneously controlled in a transmitting mode to transmit the single image displayed on the display panel through the switching panel when in the single-view mode, wherein the switching panel includes: a first substrate, a second substrate, a liquid crystal layer formed between the first and second substrates, a common electrode formed of transparent electrode on the first substrate, a main electrode formed of transparent electrode on the second substrate to drive the first region, and at least a pair of auxiliary electrodes formed of transparent electrode in the periphery of the main electrode on the second substrate to adjust the line width of the first region, the pair of auxiliary electrodes being arranged in symmetry with respect to the main electrode, wherein a width of each auxiliary electrode is smaller than a width of the main electrode, wherein the main electrode are insulated from adjacent auxiliary electrodes, such that one edge of the main electrode overlaps one edge of one of the adjacent auxiliary electrodes and another edge of the main electrode overlaps one edge of another one of the adjacent auxiliary electrodes, and wherein the each of the auxiliary electrodes is insulated from an adjacent auxiliary electrode, such that one edge of one of the auxiliary electrodes overlaps one edge of the adjacent auxiliary electrode and one edge of another one of the auxiliary electrodes overlaps one edge of another adjacent auxiliary electrode.
