    Abstract: According to one embodiment, an illumination device includes a wiring substrate, light emitting elements, a projection, and a protective layer. The main surface of the wiring substrate is divided into segment regions. Each of the segment regions is provided with n of the light emitting elements. N is greater than 1. The light emitting elements are independently driven in units of the segment regions. The protective layer is configured to protect the light emitting elements. The upper surface of the protective layer is located on the main surface side from the highest part of the projection.

    Abstract: According to an aspect, an illumination device includes: a plurality of light-emitting elements arrayed in a matrix along two directions; and a substrate on which the light-emitting elements are provided. The substrate has a plurality of partial regions. The light-emitting elements are arranged in the partial regions such that four light-emitting elements are arrayed in a two-by-two matrix along the two directions in each of the partial regions. Two light-emitting elements adjacent to each other in each of the partial regions are arranged at a first interval in one direction of the two directions. Two light-emitting elements adjacent to each other with a boundary of two partial regions adjacent to each other along the one direction interposed therebetween are arranged at a second interval in the one direction. The first interval is shorter than the second interval.
