Abstract
Provided is a method of manufacturing a display, a display, and a liquid crystal television that can improve productivity and make a grain size uniform. A method of manufacturing a display includes: (A) deriving, when a laser beam is applied to an aSi filmprovided on a substrateto thereby polycrystallize the aSi filmand form a pSi film, a relationship between energy density of the laser beam and a grain size of the pSi film; (B) selecting a predetermined range of the energy density in the derived relationship; and (C) irradiating a first area including the aSi filmwith a laser beam at energy density in the selected range of the energy density to thereby polycrystallize the aSi filmand form the pSi film
