An organic light-emitting display apparatus includes: a substrate; a thin film transistor (TFT) on the substrate and including an active layer, a gate electrode overlapping a gate region of the active layer, a source electrode overlapping a source region of the active layer, and a drain electrode overlapping a drain region of the active layer; a first electrode electrically connected to one of the source electrode or the drain electrode; a first dummy conductive pattern overlapping a dummy region of the active layer between the gate region and one of the source region or the drain region corresponding to the one of the source electrode or the drain electrode; an intermediate layer on the first electrode and comprising at least an organic emission layer; and a second electrode on the intermediate layer.

Organic light-emitting display apparatus and method of manufacturing the same

A method for crystallizing a silicon substrate includes manufacturing a crystallized silicon test substrate that is crystallized by scanning excimer laser annealing beams with different energy densities on respective areas of an amorphous silicon test substrate, irradiating a surface of the crystallized silicon test substrate using a light source, and measuring reflectivity corresponding to the respective areas of the crystallized silicon test substrate in a visible light wavelength range, extracting average reflectivities of the respective areas of the crystallized silicon test substrate in wavelength ranges corresponding to respective colors, calculating an optimum energy density (OPED) index per energy density by using a value acquired by subtracting average reflectivity of red-based colors from average reflectivity of blue-based colors, selecting an optimal energy density, and crystallizing an amorphous silicon substrate using the optimal energy density.
