    摘要: A semiconductor device in which a transistor can supply an accurate current to a load (EL pixel and signal line) without being influenced by variations is provided. A voltage at each terminal of a transistor is adjusted by a feedback circuit using an amplifier circuit. A current Idata is input from a current source circuit to the transistor, and a gate-source voltage is set by the feedback circuit so that the transistor can flow the current Idata. The feedback circuit controls the transistor to operate in a saturation region. Thus, a gate voltage required for flowing the current Idata is set. With the use of the set transistor, a current can be supplied to a load (EL pixel and signal line) with accuracy. Note that a desired gate voltage can be set quickly since the amplifier circuit is utilized.

    摘要: It is an object of the present invention to provide a liquid crystal display device which has a wide viewing angle and less color-shift depending on an angle at which a display screen is seen and can display an image favorably recognized both outdoors in sunlight and dark indoors (or outdoors at night). The liquid crystal display device includes a first portion (161) where display is performed by transmission of light and a second portion (162) where display is performed by reflection of light. Further, a liquid crystal layer (125) includes a liquid crystal molecule which rotates parallel to an electrode plane when a potential difference is generated between two electrodes of a liquid crystal element provided below the liquid crystal layer. The invention is particularly related to the layer structure of electrodes and TFTs (151) arranged on the active matrix substrate (101) of the display device.
