Abstract
A transflective liquid crystal display device is provided with a liquid crystal layer sandwiched between a first substrate with an array of switching elements and a second substrate with a black matrix so as to form a first area for a normally black display and a second area for a normally white display A first electric potential difference formed between the black matrix and both of the first common electrode and the first pixel electrode formed in the first area on the first substrate is made to be smaller than a larger one of the second electric potential difference formed between the black matrix and both of the second common electrode and the second pixel electrode formed in the second area.
