1. A lighting device comprising:
a substrate;
a plurality of light sources disposed on the substrate;
a resin layer covering the light source on the substrate;
a light blocking layer having at least one opening portion on the resin layer; and
a lens plate disposed on the light blocking layer,
wherein the lens plate includes a light transmitting portion and a plurality of convex portions arranged on one or the other surface of the light transmitting portion,
wherein a total area of the opening portion is 50% or less of an area of an emission surface through which light is emitted through the resin layer,
wherein the emission surface is an upper surface of the resin layer,
wherein the light blocking layer is disposed between the resin layer and the lens plate,
wherein an interval between the lens plate and the light blocking layer is greater than a length of the opening portion,
wherein the interval between the lens plate and the light blocking layer is provided as a first air layer; and
wherein the convex portion comprises a lenticular lens, wherein the light passing through the lens plate is illuminated as a stereoscopic surface lighting or a stereoscopic image.
