Liquid crystal display device for switching display mode between wide viewing angle and narrow viewing angle and method for fabricating the same

A liquid crystal display (LCD) device comprising:

• an LCD panel including an array substrate, a color filter substrate, and a liquid crystal layer formed between the array substrate and the color filter substrate, wherein a thin film transistor and a pixel electrode are formed on the array substrate;
• and
• a viewing angle control cell disposed on the LCD panel, the viewing angle control cell including a lower substrate having a first electrode, an upper substrate having a second electrode, and a ferroelectric liquid crystal (FLC) layer between the upper substrate and the lower substrate, wherein the ferroelectric liquid crystal (FLC) layer has a bi-stable characteristic, and a phase delay difference of the FLC layer is in a range of 3λ/4 to λ,
• wherein the array substrate, the color filter substrate, and the viewing angle control cell are each provided with a polarizing plate;
• and
• the viewing angle control cell is operative to switch the LCD device between a wide viewing angle mode when the viewing angle control cell is not driven and a narrow viewing angle mode when the viewing angle control cell is driven.
