A TFT and the like capable of realizing performances such as a low threshold voltage value, high carrier mobility and a low leak current easily. A TFT consists of a polycrystalline Si film having a small heat capacity part and a large heat capacity part, and the small heat capacity part is used at least as a channel part. The polycrystalline Si film is formed of a crystal grain film through laser annealing of an energy density with which the small heat capacity part melts completely but the large heat capacity part does not melt completely. Since the channel part is formed of large crystal grains grown from the boundaries between the small heat capacity part and the large heat capacity parts, it is possible to realize performances such as a low threshold voltage value, high carrier mobility and a low leak current by using a typical laser annealing device.

A LCD device is provided. On the input side, the collimated-light generator generates collimated light from incident light and then, the first polarizer plate of the first polarized-light controller generates first polarized light from the collimated light. The first quarter wavelength plate of the first polarized-light controller generates second polarized light from the first polarized light. The second polarized light thus generated passes through the liquid crystal layer to reach the output side. On the output side, the second polarized light passes through the second quarter wavelength plate of the second polarized-light controller and the second quarter wavelength plate thereof. Thus, the polarization state of the second polarized light is returned to its original one.
