摘要:
A lighting device has a reflection sheet; an LED having an optical element arranged at a predetermined distant position away from the reflection sheet and being used for emitting light in a direction in parallel with a light emitting surface of the lighting device in a space between the reflection sheet and the optical element; and an optical sheet provided on the light emitting surface side of the optical element. A light shielding pattern is provided at a position corresponding to the LED on the light emitting surface side of the optical element, and the light shielding pattern is configured by stacking a plurality of light shielding layers in which the light shielding layer positioned closest to the optical element side is made of a white ink, and in which at least one of the other light shielding layers is made of a mixed color ink.
