摘要： A cold-cathode tube has hitherto been used as a backlight for supplying illumination to a liquid crystal television but recently, light emitting diode pieces have been used for a backlight of a large-size liquid crystal television. For the purpose of improving the emission efficiency, flip chip mounting of the light emitting diode piece is advantageous but the mounting yield is restricted by the piece size, electrode structure and wire pattern structure, facing situations having difficulties in realizing simplified mounting and reduction of costs of members. In a liquid crystal display apparatus having a liquid crystal panel, an optical system and a light source, the light source includes a light emitting element structure having positive and negative electrodes, at least one of them being plural, and wires mounted to the positive and negative electrodes through flip chip mounting by making electrical correspondence to individual regions of the positive and negative electrodes.
