Abstract: The invention provides a high-precision display device having a reliable top- and single-gate TFT causing less current leakage. Part of a gate line 10 that crosses a semiconductor layer 103 acts as a gate electrode to form a TFT. The semiconductor layer 103 is connected to a data line 20 via a through-hole 140 on one side of the TFT and also connected to a contact electrode 107 via a through-hole 120 on the other side of the TFT. A floating electrode 30 is formed between the TFT and the through-hole 140 or between the TFT and the through-hole 120. The floating electrode 30 is formed on a layer above the semiconductor layer 103 with the use of the same material and at the same time as the gate electrode.

Abstract: Apertures are formed in the common electrode or in the pixel electrode of a liquid crystal display to form a fringe field. Storage capacitor electrodes are formed at the position corresponding to the apertures to prevent the light leakage due to the disclination caused by the fringe field. The apertures extend horizontally, vertically or obliquely. The apertures in adjacent pixel regions may have different directions to widen the viewing angle.
