Abstract
An active matrix-liquid crystal display device includes an array substrate on which pixel electrodes , signal lines with first and second conductive layers and are formed. The first conductive layers and the pixel electrodes are subject to patterning using a same mask in a same optical exposure process. The first conductive layers are wider in width than the second conductive layers . The pixel electrodes and the signal lines maintain constant relative positions on display areas thereby to hardly cause unevenness of resultant images and to enable the device to display better dignity images.
