PURPOSE:To make the size of a device smaller, by arranging plural LED elements and plural current controlling means to be connected to the elements on a common base boards. CONSTITUTION:Plural LED elements D1-D(n) are linearly arrayed in two rows on a common base board 20. On the lower surface of a wafer 22, on which the LED elements have been formed, a common cathode electrode 24 is provided, and on the upper surface of the opposite side, an anode electrode 26 is provided for each element. A light emitting part 27 is formed for each anode electrode 26. Plural thickn film register elements R1-R(n), which act as current controlling means, are arranged on both sides of the LED elements, and electrically connected to corresponding LED elements respectively. Each of the register elements is trimmed by a laser trimming unit according to the light emitting characteristics of the corresponding LED element to correct its register value. |
