Title:
表示装置
Document Type and Number:
Japanese Patent JP7459793
Kind Code:
B2
Abstract:
Provided is a display device such that the complexity of a heat-dissipation part that dissipates heat generated by a circuit element can be minimized. The display device comprises: a circuit board CB that has a driving circuit that drives a light source and a power circuit that supplies power to the driving circuit; and a heat-dissipation part 51 that faces the circuit board CB. The circuit board CB has a first circuit element group 6L that is arranged along the Y direction, and a second circuit element group 6H that is arranged along the Y direction, and is adjacent to the first circuit element group 6L in the X direction. The elements of the first circuit element group 6L have substantially the same height in the Z direction, and the elements of the second circuit element group 6H have substantially the same height in the Z direction and have a greater height than the elements of the first circuit element group 6L. The heat-dissipation part 51 has a first contact part 7a that contacts the first circuit element group 6L and a second contact part 7b that contacts the second circuit element group 6H while at a position that is further separated from the circuit board CB than the first contact part 7a.
