A first slit pattern is formed in a display substrate and a display panel of vertical alignment mode having the display substrate. The first slit pattern includes slits, a pair of projections and a pair of notches. A divergence point where the slits meet each other and an incision portion of the slits have the same function as the pair of projections in the generation of a singular point of liquid crystal. A contact hole exposing a part of an output electrode of a switching element is formed at a protective layer of an array substrate. A step recess is formed at a protective layer corresponding to a storage electrode, a divergence point of the slits is arranged to correspond to the storage electrode. The singular point of the liquid crystal is induced to occur at a regular position, and thus afterimages and spots can be prevented.

There is provided a method and an apparatus for treating return ores using plasma, capable of treating sintered return ores generated in a sintering process in a steel maker or return ores (iron ores) employed in other ironmaking process such as FINEX. The method of treating return ores using plasma includes: providing return ores sorted out by a sorting process; and bonding the return ores by fusing and agglomerating the return ores using plasma. Also, an apparatus for treating return ores using plasma includes a plasma heating device used to fuse and agglomerate sorted return ores. The return ores of a predetermined grain size are fusion-bonded and agglomerated using a flame of a plasma heating device. Particularly, the return ores can be treated in a massive amount to enhance productivity of a fusion-bonding process of the return ores. Furthermore, a great amount of sintered return ores generated in the sintering process can be subjected to a fewer number of re-treatment processes.
