Light guide plate having diffused light printed dot pattern

A lighting apparatus comprising:

• a light guide plate made of a transparent material and having a pair of faces opposing each other and an end face adjoining the faces;
• a silkscreen-printed dot pattern used to diffuse light, the pattern provided only on one face of the pair of faces of the light guide plate and formed with a special ink;
• and
• a light source disposed so as to face the end face of the light guide plate, wherein
• the face of the light guide plate provided with the silkscreen-printed pattern serves, as it is, as a light-emitting surface on one side of the light guide plate, without any other members provided thereon, and
• the lighting apparatus is configured so that a light from the light source is applied to the light guide plate and is reflected on both faces of the light guide plate and the light incident into the dot pattern is scattered outward on both sides of the light guide plate from the dots, while the light transmits through the light guide plate.
