Light-emitting device and liquid crystal display device

A light-emitting device comprising:

• a board on which a plurality of light sources are disposed;
• a sectioning member including
• a ridge part having a plurality of segments that configures a grid pattern in a top view, and
• a wall part having a plurality of portions each surrounding one or more of the plurality of light sources in the top view, and extending from the ridge part toward the board such that an interval between two adjacent ones of the portions of the wall part joining each other along one of the segments of the ridge part becomes wider toward the board;
• and
• wherein the ridge part and the wall part form a plurality of regions to surround the plurality of light sources;
• and
• one or more integrated circuits configured to drive the plurality of light sources,
• wherein the sectioning member and the one or more integrated circuits are positioned on a same side of the board on which the plurality of light sources are disposed,
• wherein a space is defined between a back surface of the sectioning member and the board, and
• wherein one of the one or more integrated circuits has a square shape or a rectangle shape in the top view, and is disposed at a position that overlaps an intersection of corresponding one of the segments of the ridge part in the space in the top view, such that sides of the square or sides of the rectangle are oblique with respect to the corresponding one of the segments of the ridge part.
