Apparatus for supplying a ribbon-like material or fabric to one or more machines for cutting the material, comprising a reel storage having a plurality of housings for storing a respective reel, elements for supplying the material to a respective machine, elements for drawing a respective reel of the ribbon-like material. A partition including portions with different thicknesses over a pixel electrode in a display region and in the vicinity of a pixel electrode layer is formed, without increasing the number of steps, by using a photomask or a reticle provided with an auxiliary pattern having a light intensity reduction function made of a diffraction grating pattern or a semi-transmissive film. An instruction insertion register may also provide an instruction in an attempt to resolve an error that occurs during operation of a state machine engine.
