Abstract
Residual direct-current charges may be accumulated and distributed non-uniformly on the built-in color filters in a displaying panel such as the liquid-crystal-on-silicon displaying device, and thus results in the non-uniformity of the internal electric field that controls the arrangement of liquid crystal molecules. To reduce residual direct-current charges so as to cause the internal electric field to be substantially uniform, the present invention provides a structure of the display panel including a plurality of shields for respectively enclosing a plurality of color filters, wherein each shield is connected to a corresponding pixel electrode by a conductive wire.
