Abstract: A laser processing apparatus and a stack processing apparatus are provided. The laser processing apparatus can perform steps selectively by switching of optical paths. The steps are a step in which a first surface of a flat-plate structure is irradiated with a laser and a step in which a surface opposite to the first surface of the structure is irradiated with the laser. The laser is a linear laser whose shape on the irradiated surface is a rectangle. By laser irradiation performed while the structure is moved in the horizontal direction, the whole or a desired region of the first surface or the opposite surface of the structure can be processed.

Abstract: A photoelectric conversion device with improved electric characteristics is provided. The photoelectric conversion device has a structure in which a window layer is formed by a stack of a first silicon semiconductor layer and a second silicon semiconductor layer, and the second silicon semiconductor layer has high carrier concentration than the first silicon semiconductor layer and has an opening.

Abstract: A display apparatus having an excellent boosting function is provided. The display apparatus is provided with a pixel having a function of adding data (a boosting function). A capacitor for boosting voltage is provided in the pixel, and data is added by capacitive coupling to be supplied to a display device. The capacitor for boosting voltage and a capacitor for retaining data are placed on top of each other, whereby the capacitance value of the capacitor for boosting voltage can be increased. Thus, the pixel can have an excellent boosting function, without significantly losing the aperture ratio or definition.

Abstract: A display device capable of performing proper display without image signal conversion is provided. In the case of high-resolution display, individual data is supplied to each pixel through a first signal line and a first transistor included in each pixel. In the case of low-resolution display, the same data is supplied to a plurality of pixels through a second signal line and a second transistor electrically connected to the plurality of pixels. When the number of image signals to be displayed is more than one and the image signals support different resolutions, display can be performed without up conversion or down conversion by switching an image signal supply path as described above.
