Abstract:
1. A liquid crystal panel comprising: a plurality of color pixels each including red (R), green (G) and blue (B) sub-pixels; and a plurality of interference (E) sub-pixels included in each of the color pixels and disposed on either the same plane or layer as the color pixels, a data driver supplying pixel driving signals to the sub-pixels of the liquid crystal panel by one line; an interference data generator generating interference data that is supplied to the interference sub-pixels; and a video data combiner inserting the interference data to video data supplied to the data driver, wherein the plurality of interference (E) sub-pixels limit light that penetrates the liquid crystal panel and travels in the side directions of the liquid crystal panel, wherein the R, G and B sub-pixels are driven by a horizontal electric field and the interference sub-pixels are driven by a vertical electric field, and wherein the interference data includes offset sub-pixel data supplied to the interference sub-pixels for a wide viewing angle mode and interference sub-pixel data supplied to the interference sub-pixels for a narrow viewing angle mode.
