Array substrate for mounting chip and method for manufacturing the same
First Claim
1. An array substrate for mounting a chip to a circuit board, the array substrate comprising:
- a plurality of conductive parts arranged in one direction, whereon a plurality of chips are mounted in the one direction, each of the plurality of conductive parts having a chip-mounting surface, and a back surface opposite the chip-mounting surface for mounting the array substrate to the circuit board;
one or more insulating parts alternately arranged with the plurality of conductive parts for electrically separating the plurality of conductive parts,protrusion parts whose heights are different from that of a surface of the conductive parts whereon the chip is mounted, the protrusion parts being arranged at both ends and a central portion of the array substrate; and
concave parts depressed in a lateral direction with respect to side surfaces of the array substrate, the concave parts being arranged only at the both ends and the central portion where the protrusion parts are arranged.

Abstract
Provided is an array substrate for mounting a chip. The array substrate includes a plurality of conductive layers unidirectionally stacked with respect to an original chip substrate; a plurality of insulating layers alternately stacked with the plurality of conductive layers, and electrically separate the plurality of conductive layers; and a cavity having a groove of a predetermined depth with respect to a region including the plurality of insulating layers in an upper surface of the original chip substrate. Accordingly, since the optical device array of a single structure is used as a line source of light, an emission angle emitted from the optical device is great, it is not necessary to form an interval for supplying an amount of light, and a display device can be simply constructed. Further, since it is not necessary to perform soldering a plurality of LED packages on a printed circuit board, a thickness of a back light unit can be reduced.
