An electronic gaming console is illustrated having a console cabinet 10 including a prize display 12, a coin entry slot 13, a payout tray 14 and internally mounted game control processor circuits. Concrete is poured into a casting mold with a planar bottom for producing a planar underside. Alternatively, a discharge port may be provided in one of the side wall portions. This is especially effective in virtual machines that operate with limited memory resources. Each switch point includes the playback offset associated with the corresponding GOP and the data packet storing the key frame of the corresponding GOP. The method includes steps of: forming a TFT on a base substrate ; forming a color film layer pattern on the base substrate having the TFT formed thereon; forming a pattern which includes a color film via hole on the color film layer through a patterning process, the patterning process includes an ashing process; and forming a pattern comprising a pixel electrode on the base substrate.
