One embodiment of the present invention provides a highly reliably display device in which a high mobility is achieved in an oxide semiconductor. A first oxide component is formed over a base component. Crystal growth proceeds from a surface toward an inside of the first oxide component by a first heat treatment, so that a first oxide crystal component is formed in contact with at least part of the base component. A second oxide component is formed over the first oxide crystal component. Crystal growth is performed by a second heat treatment using the first oxide crystal component as a seed, so that a second oxide crystal component is formed. Thus, a stacked oxide material is formed. A transistor with a high mobility is formed using the stacked oxide material and a driver circuit is formed using the transistor.

A gate electrode is formed on a TFT substrate, while a gate insulating film is overlaid on the gate electrode. A pixel electrode which is divided into segments is formed on the gate insulating film. The segments of the pixel electrode are normally interconnected by a source electrode. An inter-layer insulating film, on which a common electrode including slits is formed, is overlaid on the pixel electrode. In a case where the common electrode and one of the segments of the pixel electrode are conductively interconnected by a conductive foreign substance, the other segments of the pixel electrode are allowed to operate by disconnecting the conducted segment of the pixel electrode from the source electrode. Thus, one pixel is prevented from lapsing into a full pixel defect.

A pixel of a liquid crystal panel is constituted by three subpixels. When the gradation of the pixel can be represented by only the subpixel, with setting the gradations of the subpixels to their minimum gradations, the gradation of the subpixel is determined. When the gradation of the pixel is represented by the subpixels, with setting the gradation of the subpixel to its maximum gradation and setting the gradation of the subpixel to its minimum gradation, the gradation of the subpixel is determined so that the ratio of the transmittance of the subpixel to the transmittance of the pixel is less than a limit value. When the gradation of the subpixel cannot be determined to satisfy a condition, with setting the gradation of the subpixel to its minimum gradation, the gradations of the subpixels are determined to obtain a gradation higher than or equal to the gradation of the pixel.
