Abstract:
A method of producing a liquid crystal display panel, comprising the steps of:irradiating a location, in which a horizontal scanning circuit portion is to be formed, of an amorphous silicon thin film panel to be crystallized with a specific number of shots of a laser beam having a uniform energy density distribution and having a rectangular shape of a long-side larger than a width of said amorphous silicon thin film panel and a short-side larger than a short-side of said horizontal scanning circuit portion, in a state in which a relative positional relationship between said amorphous silicon thin film panel and said laser beam is fixed; and irradiating a location, in which a vertical scanning circuit portion and a pixel portion are to be formed, of said amorphous silicon thin film panel with said laser beam while moving said laser beam relative to said amorphous silicon thin film panel along the length direction of said amorphous silicon thin film panel.
