Display apparatus for displaying specific pattern, has emission structure region containing several emission structure portions in which emission light quantity in incident to predetermined direction is maximum in direction of light source

摘要

In a display device (1), a light guide plate (2) includes a first emission structure region including a plurality of first emission structures (6 and 8) in which an incident direction for maximizing an amount of light emitted in a predetermined direction is a direction of a first light source (4), a second emission structure region including a plurality of second emission structures (9 and 10) in which the incident direction for maximizing the amount of light emitted in the predetermined direction is a direction of a second light source adjacent to the first light source, and a third emission structure region including a plurality of third emission structures (11 to 13) in which the incident direction for maximizing the amount of light emitted in the predetermined direction is a direction between the first light source and the second light source, and the third emission structure region is disposed between the first emission structure region and the second emission structure region.
