The utility model provides a light guide plate capable of mitigating nonuniform linear brightness of connection portion of ink guns, an edge light type area source apparatus and a transmission type image display device. According to the light guide plate (1) provided in an embodiment of the utility model, as least one light guide plate base material surface of a printing apparatus with more than two ink guns (5a,5b) arranged on an arrangement direction of a plurality of nozzles (51) is formed with a light guide plate with a light distribution pattern coating a plurality of light reflection points (12a, 12b). Adjacent ink guns (5a,5b) are configured in a way that part of the nozzles (51) are superposed on a direction intersected with an arrangement direction. In a region (Ro) formed by superposed portion of the adjacent ink guns in the light distribution pattern, the light reflection point (12a) formed by the ink gun (5a) at one side and the light reflection point (12b) formed by the ink gun (5b) at the other side are mixed together.
