摘要： A transreflective or “semi-transmissive” liquid crystal display (LCD) device of the vertical alignment (VA) type is disclosed. The VA-LCD device includes a pair of spaced-apart substrates with a layer of liquid crystal (LC) material sandwiched therebetween. The LCD device also includes a polarization plate provided on one of the substrates, another polarization plate on the other substrate, and a matrix of rows and columns of pixels formed between the substrates. Each pixel has a reflection part and a transmission part. The LC layer is variable in thickness so that its portion at the transmission part is thicker than a portion at the reflection part. At the reflection part, an internal retardation plate having an optical phase difference is disposed between the LC layer and its associated substrate. This plate forms an angle of about 45 degrees with the absorption axis of each polarization plate.
