PURPOSE:To reduce a horizontal change in color tone when constructing a LED display or a display panel by allowing a straight line which connects LED chips to cross aslant with the alignment direction of leads for bonding. CONSTITUTION:On a oval LED mounting section 2 which is united with a lead for mounting 1 at its one end, for example, a red LED chip 3 and a green LED chip 4 are secured at the place deviated from the major axis of the section 2. On both ends of the lead 1, leads for bonding 5 and 6 are installed at a specified space. The leads 5 and 6 are connected with the red LED chip 3 and the green LED chip 4 respectively with a bonding wire 7, 8. At that time, a straight line y1 which connects the center of the LED chip 3 and that of the LED chip 4 crosses aslant (for example, crosses at an angle of 45 deg.) with the alignment direction A of the leads 1, 5 and 6. Therefore, a horizontal change in color tone can be reduced when constructing a LED display or a display panel. |
