摘要： The liquid crystal display device performs display by changing the number of gray scales depending on external light intensity, and switches the display mode in accordance with a content to be displayed on a display. By controlling a display mode-specific video signal generation circuit depending on external light intensity, an inputted video signal is outputted as an analog value, is outputted with a digital value of a binary, or is outputted with a multiple digital value. As a result, display gradation of a pixel changes timely. Accordingly, a clear image can be displayed. For example, a display device which secures visibility can be obtained in a wide range from under fluorescent light in a dark place or indoor to under outdoor sunlight.

摘要： It is an object of one embodiment of the present invention to manufacture a light-emitting display device by simplifying a manufacturing process of a transistor, without an increase in the number of steps as well as the number of photomasks as compared to those in the conventional case. A step for processing a semiconductor layer into an island shape is omitted by using a high-resistance oxide semiconductor which is intrinsic or substantially intrinsic for the semiconductor layer, used to form transistors. Formation of an opening in the semiconductor layer or an insulating layer formed over the semiconductor layer and etching of an unnecessary portion of the semiconductor layer are performed at the same time; thus, the number of photolithography steps is reduced.

摘要： In a display device having driving circuits formed on the same substrate where pixels are formed, the lateral frame area of the display device is reduced. A gate signal line driving circuit is placed in parallel with a source signal line driving circuit, so that no driving circuits are provided in at least two opposing directions out of four directions with respect to a pixel region. With the above-described structure, the area the gate signal line driving circuit occupies in prior art is removed to reduce the width (side to side) of the display device. Therefore a display device that has a small frame area in the lateral direction can be provided.

摘要： In a conventional analog buffer circuit composed of polycrystalline semiconductor TFTs, a variation in the output is large. Thus, a measure such as to provide a correction circuit has been taken. However, there has been such a problem that a circuit and driver operation are complicated. Therefore, a gate length and a gate width of a TFT composing an analog buffer circuit is set to be larger. Also, a multi-gate structure is adopted thereto. In addition, the arrangement of channel regions is devised. Thus, the analog buffer circuit having a small variation is obtained without using a correction circuit, and a semiconductor device having a small variation can be provided.
