In a conventional solar cell, it has been difficult to ensure a sufficient light absorption and simultaneously to prevent current loss due to the reduction of the moving distance of electrons and holes. As a means for solving this difficulty, a plurality of a p-i-n junctions are stacked through an insulating film and are connected in parallel with each other using through-electrodes. In this case, the through-electrodes and the p-i-n junctions are connected through the p-layer or the n-layer, thereby moving electrons and holes in opposite directions and generating output current. In addition, the i-layer is made thicker than the p-layer and the n-layer in each of the p-i-n junctions, thereby ensuring a sufficient light absorption and simultaneously preventing current loss.

There is provided a method for fabricating an image display device having an active matrix substrate including high-performance transistor circuits operating with high mobility as drive circuits for driving pixel portions which are arranged as a matrix. The portion of a polysilicon film formed in a drive circuit region DAR1 provided on the periphery of the pixel region PAR of the active matrix substrate SUB1 composing the image display device is irradiated and scanned with a pulse modulated laser beam or a pseudo CW laser beam to be reformed into a quasi-strip-like-crystal silicon film having a crystal boundary continuous in the scanning direction so that discrete reformed regions each composed of the quasi-strip-like-crystal silicon film are formed. In virtual tiles TL composed of the discrete reformed regions, drive circuits having active elements such as thin-film transistors or the like are formed such that the channel directions thereof coincide with the direction of crystal growth in the quasi-strip-like-crystal silicon film.

The present invention provides a liquid crystal display device with high image visibility at low power consumption and produced at low cost by using an interlayer dielectric film, which has low dielectric constant, high heat-resistant property, high optical transmissivity, high film thickness and high flattening property produced at low cost. An organic siloxane dielectric film is used as an interlayer dielectric film of the liquid crystal display device. A ratio of nitrogen content to silicon content (Ni content/Si content) in the interlayer dielectric film is controlled to 0.04 or more in the element ratio. The limiting film thickness to suppress and limit the cracking caused by the thickening of the interlayer dielectric film is set to 1.5 μm or more.
