Abstract
A liquid crystal display device comprising a display screen and liquid crystal element-driving circuits. The display screen has an effective display region with a plurality of transparent electrodes on both sides of liquid crystal elements to make characters visible and a non-display region that is the region other than the effective display region. The driving circuits are divided into two groups. One group is for driving the liquid crystal elements in the effective display region to display desired characters, and the other group is for driving the liquid crystal elements in the non-display region to make the non-display region dark or bright.
