Abstract
An active matrix-liquid crystal display device includes an array substrate 100 on which pixel electrodes 151, signal lines 103 with first and second conductive layers 103a and 103b are formed. The first conductive layers 103a and the pixel electrodes 151 are subject to patterning using a same mask in a same optical exposure process. The first conductive layers 103a are wider in width than the second conductive layers 103b. The pixel electrodes 151 and the signal lines 103 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.
