Lighting device and display device

A lighting device comprising:

• a light-guiding plate constituted of a plate-shaped member;
• and
• a light source that is disposed opposite an end face of the light-guiding plate and emits light toward the end face, wherein
• the light-guiding plate includes a light entrance surface through which light from the light source enters, an entrance opposite surface located opposite to the light entrance surface, a light exit surface that is one of a pair of plate surfaces and through which the light exits, and an exit opposite surface located opposite to the light exit surface, and the light-guiding plate has a notch formed by notching a part thereof,
• a region between the notch and the entrance opposite surface is a shielded region where the notch blocks light guided through inside the light-guiding plate from the light entrance surface toward the entrance opposite surface,
• a condensing member having a reflecting surface that reflects, in a condensing manner toward the shielded region, light having leaked out through the exit opposite surface is provided opposite the exit opposite surface of the light-guiding plate, and
• the notch is a through-hole bored through the light-guiding plate.
