摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： With an increase in the definition of a display device, the number of pixels is increased, and thus the numbers of gate lines and signal lines are increased. The increase in the numbers of gate lines and signal lines makes it difficult to mount an IC chip having a driver circuit for driving the gate line and the signal line by bonding or the like, which causes an increase in manufacturing costs. A pixel portion and a driver circuit driving the pixel portion are provided over the same substrate. The pixel portion and at least a part of the driver circuit are formed using thin film transistors in each of which an oxide semiconductor is used. Both the pixel portion and the driver circuit are provided over the same substrate, whereby manufacturing costs are reduced.

摘要： A driver circuit includes a circuit 200, a transistor 101—1, and a transistor 101—2. A signal is selectively input from the circuit 200 to a gate of the transistor 101—1 and the transistor 101—2, so that the transistor 1011 and the transistor 101—2 are controlled to be on or off. The transistor 101—1 and the transistor 101—2 are turned on or off; thus, the wiring 112 and the wiring 111 become conducting or non-conducting.

摘要： When a light-emitting element emits light for a long time, characteristics thereof change and current flowing therethrough is reduced even in the same voltage is applied. In particular, in a case of a display device with light-emitting element, there is a problem such that burn-in is generated in a display screen. A burn-in correction period in which characteristics of a light-emitting element in each pixel are detected is provided in addition to a normal driving period in which an image is displayed. The light-emitting element can emit light which compensates the changes in the characteristics, by correcting video signals inputted to each pixel in the normal driving period according to the characteristics of the light-emitting elements obtained in the burn-in correction period.
