Abstract: PROBLEM TO BE SOLVED: To improve the reliability of an active matrix substrate by preventing the corrosion, etc., of lead-out wiring by covering the wiring with a gate insulating film or ITO without adding any patterning process and, in addition, improving the manufacturing yield of the substrate. SOLUTION: This active matrix substrate is provided with a source electrode 14 and a drain electrode 15 which are arranged above an insulating substrate 11 with a prescribed clearance in between; an a-Si film 17, a gate insulating film 18, and a gate electrode 19 successively laminated upon the electrodes 14 and 15; and an ITO 20 having a first portion which is laminated upon the gate electrode 19 and has the same patterned surface as the electrode 19 has and a second portion which is formed to partially cover the source electrode 14 and forms a picture element electrode. The substrate is also provided with a data line 16 which is connected to the drain electrode 15 and covered with another gate insulating film 18.

Abstract: PROBLEM TO BE SOLVED: To reduce blurred picture in animated picture display and to obtain a satisfactory picture quality free from ghost. SOLUTION: This liquid crystal display device is provided with a control means which, in one period in a cycle of displaying one picture, controls a gate line driving means 2 so as to select a gate line for each of the first and the second pixel array for the purpose of displaying a picture on a liquid crystal panel; which controls the first and the second data line driving means 4a, 4b so that a picture signal for showing a picture is supplied to the first and the second data line group; which, in a separate period different from one in the same cycle as the one period, controls the gate line driving means 2 so as to select the gate line once more for each of the first and the second pixel array; and which controls the first and the second data line driving means 4a, 4b so that a non-picture signal having a prescribed electric potential and different from the picture signal is supplied to the first and the second data line group.
