Flat-type light source apparatus, liquid crystal display apparatus using the same, and method of inspecting the liquid crystal display

A method of inspecting a liquid crystal display apparatus with a back-light unit, comprising the steps of:

• preparing a liquid crystal display apparatus comprising a flat light source apparatus used as the back-light unit, including a light source, a light emitting unit configured to output light from said light source through a front surface, a frame for containing said light source and said light emitting unit, a conductive pad mounted on a back outer surface or a side outer surface of said frame, and a power supply terminal of said light source connected to said conductive pad to light up said light source through said conductive pad;
• a liquid crystal panel with liquid crystal filled between two insulating substrates facing each other which is fixed to a viewing side of said flat light source apparatus, and said liquid crystal panel is configured to transmit the light from said flat light source to a display surface;
• and an outer housing disposed form an outer shell of the liquid crystal display apparatus, said outer housing framing said liquid crystal panel and enclosing said flat light source apparatus, wherein said conductive pad is accessible from outside said outer housing;
• bringing said conductive pad into contact with a power supply terminal of an inspection device placed on a outer surface of said inspection device in a position corresponding to said conductive pad;
• and
• supplying a power from said power supply terminal of said inspection device to a power supply terminal of said light source through said conductive pad to light up said light source.
