Abstract:
A transparent reflective liquid crystal display device using light generated from external light sources and a backlight unit, the device comprising:a first circular polarizer for transmitting circular-polarized light having a first direction input from the backlight unit while reflecting a circular-polarized light having a second direction contrary to the first direction; a second circular polarizer for transmitting the circular-polarized light having the second direction while reflecting the circular-polarized light having the first direction; a first circular-polarizing color filter, being provided at least partly within the second circular polarizer, for extracting circular-polarized light of a specific visible light wavelength band in the circular-polarized light having the first direction; and a reflecting member arranged at one side of the second circular polarizer to reflect the external light and having at least one hole formed therein in substantial alignment with the first circular-polarizing color filter to transmit the circular-polarized light of the specific visible light wavelength band via the at least one hole.
