Abstract: A semiconductor device including a non-volatile memory cell including a writing transistor which includes an oxide semiconductor, a reading transistor which includes a semiconductor material different from that of the writing transistor, and a capacitor is provided. Data is written or rewritten to the memory cell by turning on the writing transistor and supplying a potential to a node where a source electrode (or a drain electrode) of the writing transistor, one electrode of the capacitor, and a gate electrode of the reading transistor are electrically connected to each other, and then turning off the writing transistor so that the predetermined amount of charge is held in the node. Further, when a transistor whose threshold voltage is controlled and set to a positive voltage is used as the reading transistor, a reading potential is a positive potential.

Abstract: Provided is to secure a data-writing period to a source line and reduce the number of the IC chips used. N image data (e.g., three image data, RGB) are sequentially input to one input terminal. Three switches, three first memory elements, three transfer switches, three second memory elements, and three buffers are connected in parallel to the input terminal. The three switches are turned on respectively. RGB image data are held in the three respective first memory elements. In a selection period of a gate line of an (m−1)-th row, image data of an m-th row are written to the first memory elements. When the three transfer switches are turned on in a selection period of a gate line of an m-th row, the image data are transferred to and held in the second memory elements. Then, the image data are output to each source line through each buffer.

Abstract: It is an object to provide a transmissive liquid crystal display device in which power consumption is reduced and deterioration in display quality is suppressed. As a backlight, a surface-emission light source is employed. The light source is a light source which performs surface light emission, so that the light emission area is large. Accordingly, the backlight can effectively radiate heat. Thus, even in the case where an image signal is not input to a pixel for a long period, the pixel can hold the image signal. In other words, both a reduction in power consumption and a suppression of deterioration in display quality can be realized.

Abstract: To provide a liquid crystal display device which can perform image display in both modes: a reflective mode where external light is used as an illumination light source; and a transmissive mode where a backlight is used. In one pixel, a region where incident light through a liquid crystal layer is reflected to perform display (reflective region) and a region through which light from the backlight passes to perform display (transmissive region) are provided, and image display can be performed in both modes: the reflective mode where external light is used as an illumination light source; and the transmissive mode where the backlight is used as an illumination light source. In addition, two transistors connected to respective pixel electrode layers are provided in one pixel, and the two transistors are separately operated, whereby display of the reflective region and display of the transmissive region can be controlled independently.

Abstract: To improve the image quality of a liquid crystal display device. In the liquid crystal display device, writing of an image signal and the turning on the backlights are not sequentially performed in the entire pixel portion but are sequentially performed per specific region of the pixel portion. Thus, it is possible to increase the frequency of input of an image signal to each pixel of the liquid crystal display device. Accordingly, deterioration of display such as color break generated in the liquid crystal display device can be suppressed, and the image quality can be improved.
