Abstract: To provide a liquid crystal display device suitable for a thin film transistor which uses an oxide semiconductor. In a liquid crystal display device which includes a thin film transistor including an oxide semiconductor layer, a film having a function of attenuating the intensity of transmitting visible light is used as an interlayer film which covers at least the oxide semiconductor layer. As the film having a function of attenuating the intensity of transmitting visible light, a coloring layer can be used and a light-transmitting chromatic color resin layer is preferably used. An interlayer film which includes a light-transmitting chromatic color resin layer and a light-blocking layer may be formed in order that the light-blocking layer is used as a film having a function of attenuating the intensity of transmitting visible light.

Abstract: In a light-emitting device where reflective electrodes are regularly arranged, occurrence of interference fringes due to reflection of light reflected by the reflective electrode is inhibited. A surface of the reflective electrode of a light-emitting element is provided with a plurality of depressions. The shapes of the plurality of depressions are different from each other and do not have rotational symmetry. Irregularity of the surface shape of the reflective electrode is increased, which inhibits interference of light reflected by the reflective electrode. To form the plurality of depressions in the surface of the reflective electrode, for example, a surface of an insulating layer that is a base of the reflective electrode is made uneven. Reflecting the surface shape of the insulating layer, the reflective electrode has an uneven surface.

Abstract: To provide a display device with a novel structure that can achieve both thickness reduction and favorable display quality. In a structure of a display device including a liquid crystal layer between a pixel electrode and a counter electrode, a common electrode and an electrode of a capacitor in a touch sensor on the counter electrode side are formed integrally and supplied with a pulse signal. On the element substrate side, a signal to be supplied to a capacitor line that forms a capacitance with the pixel electrode is in conjunction with the pulse signal so as to cancel a change in an electric field applied to the liquid crystal layer. Such a structure can achieve a display device with a touch sensor function that can cancel a change in an electric field applied to a liquid crystal layer even when the electric field is changed by a pulse signal.

Abstract: A semiconductor device including an oxide semiconductor and an organic resin film is manufactured in the following manner. Heat treatment is performed on a first substrate provided with an organic resin film over a transistor including an oxide semiconductor in a reduced pressure atmosphere; handling of the first substrate is performed in an atmosphere containing moisture as little as possible in an inert gas (e.g., nitrogen) atmosphere with a dew point of lower than or equal to −60° C., preferably with a dew point of lower than or equal to −75° C. without exposing the first substrate after the heat treatment to the air; and then, the first substrate is bonded to a second substrate that serves as an opposite substrate.
