METHOD FOR DESIGNING MASK AND METHOD FOR FORMING PANEL

摘要

PURPOSE: A method for designing a mask is provided to define one mask into the first area and the second area, and to design the first panel mask in the first area of the mask, then to design the second panel mask area in the second area, thereby magnifying usage efficiency of a substrate. CONSTITUTION: When a large-sized panel(22) is out of a mask(23) or the large-sized panel(22) is disposed on a substrate by using the one mask(23), a repeated area is designed on the large-sized panel(22) in a central part of the mask(23). The first and second non-repeated regions are designed in the mask on both sides of the first repeated area. The first non-repeated region refers to an area that a black matrix and a pad at the left end of the panel(22) occupy. The second non-repeated area refers to an area that a black matrix at the right end occupies. The repeated area refers to other areas except the first and second non-repeated areas.
