摘要：
A liquid crystal display device capable of displaying in multiple colors, and a method for driving the liquid crystal display device using a typical monochrome liquid crystal driving IC. A display portion of a birefringence color liquid crystal display device has a usual letter display portion (41) for displaying letters in a single color and a mark display portion (42) for displaying a variety of colors. A liquid crystal cell is driven by supplying scanning signals to scanning electrodes for the letter display portion (41) and data signals to scanning electrodes for the mark display portion (42).
