Abstract:
A transflective liquid crystal display (LCD) device, comprising:first and second substrates facing and spaced apart from each other; a first polarizer formed under the first substrate; a half wave plate and a second polarizer that are formed in series on the second substrate; a backlight device being adjacent to the first polarizer; a common electrode on a surface of the second substrate facing the first substrate; a pixel electrode formed on the first substrate and corresponding to each pixel, the pixel electrode is divided into a transmissive portion and a reflective portion; a liquid crystal layer interposed between the first and second substrates, wherein a thickness of the liquid crystal layer between the common electrode and the transmissive portion of the pixel electrode is more than 1.5 and less than 2.5 times larger than a thickness of the liquid crystal layer between the common electrode and the reflective portion of the pixel electrode; and, within a range of about 10 degrees to 17.5 degrees wherein a slow axis of the half wave plate is disposed at an angle â€œ&thgr;â€  from a transmissive axis of the second polarizer; and wherein a transmissive axis of the first polarizer is disposed at the angle â€œ2&thgr;â€  from the transmissive axis of the second polarizer.
