Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a light guide plate capable of reducing the non-uniformity of linear luminance in a connection portion of inkjet heads.SOLUTION: In a manufacturing method of a light guide plate, neighboring heads 5a, 5b in a printing device are arranged so that a part of a plurality of nozzles 51 may be overlapped, K-pieces of nozzle numbers are applied to the overlapping nozzles 51 of the neighboring heads 5a, 5b from one head 5b to the other head 5a, K-pieces of arbitrary continuous sequence of numbers out of " van der Corput" sequence are obtained, and the sequence is correlated to the printing row of the k-rows. The sequence number is applied to the sequence in an ascending order or descending order of the numbers. A light distribution pattern composed of a plurality of light reflection dots 12a, 12b is printed on the base material of the light guide plate so that, in the k-row of the printing row, the nozzle numbers corresponding to the sequence number of the sequence correlated to the printing row of the k-row may be a printing start position of the other head 5a.
