Abstract: PROBLEM TO BE SOLVED: To prevent picture quality from failure such as deterioration caused by increase in an electric power due to a leakage current of a parasitic transistor or coming-off of a signal line from a specified potential. SOLUTION: This is a liquid crystal display device wherein thin film field effect transistors(TFT) 17 and picture element electrodes 16 of a forwardly staggered structure are arranged in a matrix form, in the neighborhood of each intersection part of plural main scanning lines 12 and plural signal lines 11, and the TFTs 17 turned on by the supply of a scanning signal voltage is supplied with a DC potential through a common electrode line 10. Thus, the DC potential is written in the picture element electrodes 16 via the TFTs turned on. Such common electrode lines 10 are alternatively arranged in parallel in a state perpendicular to the scanning line 12.  According to this constitution, even if a parasitic transistor is formed between adjacent common electrode lines 10 via the main scanning line 12, a same potential is applied to each common electrode line 10, therefore, no potential difference occurs between the drain and source of the parasitic transistor.
