摘要

PROBLEM TO BE SOLVED: To provide a method of adjusting the arrangement position of a diffusing plate by which the unevenness of brightness is reduced, and to provide a backlight unit having excellent optical characteristics, an electro-optic device, and an electronic equipment.;SOLUTION: The diffusing plate 43 has an attaching hole 51 as a detection mark showing a detection start position and includes a moving step for moving the diffusing plate 43, a first detection step for detecting the position of the attaching hole 51, a second detection step for detecting the position of a vacuum fluorescent tube 41 as a light source, a measuring step for measuring the distance between the position of the attaching hole 51 detected in the first detection step and the position of the vacuum fluorescent tube 41 detected in the second detection step and an adjustment step for adjusting the position of the diffusing plate 43 by comparing the distance detected in the detection steps with a distance based on a design information.;COPYRIGHT: (C)2007,JPO&INPIT
