Abstract The production method of homogeneous light pattern of backlight plate is characterized by that the backlight plate is a translucent plate approaching to flat form, it comprises two mutual parallel transmission faces and incident edge which is approaching to linear and positioned at one side of two fransmission faces, when the visible light is passed through the incident edge and streamed into the backlight plate, the visible light can be penetrated into the backlight plate translucent plate and streamed from two transmission faces of backlight plate. Said method utilizes the rolling tool with several salient points to roll-pressing transmission faces of backlight plate to form several pits on every transmission face, thest pit-formed pattern is the homogeneous light pattern of backlight plate, and these pits can make light implement homogenization.
