This invention provides a semiconductor device having high operation performance and high reliability. An LDD region 707 overlapping with a gate wiring is arranged in an n-channel TFT 802 forming a driving circuit, and a TFT structure highly resistant to hot carrier injection is achieved. LDD regions 717, 718, 719 and 720 not overlapping with a gate wiring are arranged in an n-channel TFT 804 forming a pixel unit. As a result, a TFT structure having a small OFF current value is achieved. In this instance, an element belonging to the Group 15 of the Periodic Table exists in a higher concentration in the LDD region 707 than in the LDD regions 717, 718, 719 and 720.

A liquid crystal display device includes liquid crystal pixels, signal line groups each including a predetermined number of signal lines, and a drive circuit which selects the pixels on a row-by-row basis and drives the pixels of the selected row via the signal lines. The drive circuit includes a signal line driver which outputs a predetermined number of pixel voltages for each group driving period while the pixels of each row are being selected, a multiplexer which distributes to each signal line group the pixel voltages output from the signal line driver, and a controller which controls the multiplexer to electrically connect all of the signal line groups to the signal line driver and electrically disconnect the signal line groups one by one from the signal line driver for each group driving period, in a selection period of the pixels of an initial row that requires polarity inversion.

In an active matrix type liquid crystal display device, in which functional circuits such as a shift register circuit and a buffer circuit are incorporated on the same substrate, an optimal TFT structure is provided along with the aperture ratio of a pixel matrix circuit is increased. There is a structure in which an n-channel TFT, with a third impurity region which overlaps a gate electrode, is formed in a buffer circuit, etc., and an n-channel TFT, in which a fourth impurity region which does not overlap the gate electrode, is formed in a pixel matrix circuit. A storage capacitor formed in the pixel matrix circuit is formed by a light shielding film, a dielectric film formed on the light shielding film, and a pixel electrode. Al is especially used in the light shielding film, and the dielectric film is formed anodic oxidation process, using an Al oxide film.

A liquid crystal display includes pixels, driver circuits, and a control circuit. The control circuit sets, in a one-frame period, a first period and a second period shorter than the one-fame period and partly overlapping the first period. The control circuit controls the driver circuits, causing them to write non-video signals for the pixels in the first period, to write video signals for the driver circuits in the second period, and to write the non-video signals and the video signals alternately in units of one or more horizontal periods in a part of the first period, which overlaps the second period, and to output the non-video signals and the video signals alternately in units of one or more horizontal periods in a part of the first period, which does not overlap the second period, and to write the non-video signals in a period for writing non-video signals.
