Patent ID: 8748326

Claim:
A device for forming a low-temperature polysilicon film comprising: a plurality of microlenses arranged one-dimensionally or two-dimensionally; a laser-light-generating source; a light guide section for guiding laser light from the laser-light-generating source to said microlenses so as to condense said laser light onto an amorphous silicon film by said microlenses; and a plurality of, masks, each of the masks being arranged for each of the microlenses, and each including a plurality of transmission areas for transmitting said laser light and a plurality of light-blocking areas for blocking said laser light in a two-dimensional arrangement on said masks, wherein said transmission areas and said light-blocking areas are disposed alternatingly in one direction and an other direction crossing said one direction, such that the transmission areas are not adjacent to one another and the light-blocking areas are not adjacent to one another, and wherein the masks are disposed between the light guide section and the microlenses.
