Abstract
A process for producing an image display device using a thin film semiconductor device is provided which includes forming a polycrystalline semiconductor thin film on a substrate. A substantially belt-shaped crystal is formed which is crystallized so as to grow crystal grains in a direction substantially parallel to a scanning direction of a CW laser beam by scanning the CW laser beam along the substrate, thereby irradiating the CW laser beam on portions of the polycrystalline semiconductor thin film formed onto the substrate.
