Light emitting module, backlight unit and liquid crystal display device

A light emitting module that supplies light to a light guide plate, the light emitting module comprising:

• a plurality of light emitting elements;
• and a support board which arranges and supports the light emitting element;
• wherein of the plurality of the light emitting elements, a group of linear light emitting elements that are arranged in a line is included, and at least a deviating light emitting element that deviates from the line toward a light emitting side of the light emitting element is included;
• and
• a light emitting surface the deviating light emitting element comes into contact with a side surface of the light guide plate, so that light emitting surfaces of the group of linear light emitting elements do not come into contact with the side surface of the light guide plate, a position of the group of linear light emitting elements is set at a position away from the side surface of the light guide plate by a predetermined distance, and the light emitting module meets the following conditional formula (1);
• AD<DD conditional formula (1)
• where
• AD:
• a distance of a positional tolerance between the light emitting elements that occurs in a direction which intersects the line of the light emitting elements, and
• DD:
• a distance between the deviating light emitting element and the group of the light emitting elements in a direction that intersects the line of the light emitting elements.
