    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: A liquid crystal display device using a liquid crystal exhibiting a blue phase and having a novel structure, and a method for manufacturing the liquid crystal display device. A plurality of structure bodies (also referred to as ribs, protrusions, or projecting portions) are formed over the same substrate, and a pixel electrode and an electrode (a common electrode at a fixed potential) corresponding to the pixel electrode are formed thereover. An electric field is applied to the liquid crystal layer exhibiting a blue phase by using the pixel electrode that has an inclination and the electrode corresponding to the pixel electrode, which also has an inclination. A shorter distance between the adjacent structure bodies allows a strong electric field to be applied to the liquid crystal layer, which results in a reduction in power consumption for driving the liquid crystal.
