摘要:
A reflective-transmissive liquid crystal display (LCD) device with an improved display quality is achieved by forming a reflective area and a transmissive area having a cell gap greater than greater than that of the reflective area. A liquid crystal layer is disposed in a liquid crystal cell between the first and second substrates. The liquid crystal molecules are normally aligned at an angle equal to greater than about 45° with respect to a line parallel to the first substrate. The LCD device operates in a normally black mode.

A liquid crystal display panel includes a liquid crystal layer having a twist angle of ±10 degree. An upper polarizer is disposed over an upper substrate of the liquid crystal display panel, and includes an absorption axis forming at an angle of 47±10 degree in a clockwise direction with respect to a major axis. An upper λ/2 retardation film is disposed between the upper substrate and the upper polarizer, and includes Δnd1 of 260±10 nm and a slow axis forming at an angle of 166±10 degree in the clockwise direction with respect to the absorption axis. An upper λ/4 retardation film is disposed between the upper substrate and the upper λ/2 retardation film, and includes Δnd2 of 140±10 nm and a slow axis forming at an angle of 111±10 degree in the clockwise direction with respect to the absorption axis. Therefore, the optical condition of the optical film assembly is optimized to improve an image display quality.
摘要:
In an LCD apparatus, a reflecting plate, which is formed on a pixel electrode connected to a switching device formed on an array substrate, defines a first area from which a natural light is reflected and a second area through which an artificial light is transmitted. The reflecting plate is partially extended to and overlapped with the second area depending upon a rubbing direction of the array substrate. Thus, the reflective-transmissive type LCD apparatus may prevent occurrence of the afterimage, and may enhance a contrast ratio thereof when operated in a transmissive mode.

摘要:
In a liquid crystal display apparatus, a lower substrate has a transmissive electrode formed in a transmissive area of a first substrate and a reflective electrode formed in a reflective area of the first substrate. An upper substrate has a second substrate, a first insulating layer formed on the second substrate corresponding to the transmissive area, a common electrode formed on the first insulating layer and the second substrate corresponding to the reflective area, and a second insulating layer formed on the common electrode corresponding to the reflective area. Accordingly, the liquid crystal display apparatus may have a uniform cell gap, thereby improving a reflectance and a transmittance thereof.
