Abstract
A light source portion for a backlight module that emits light to be incident on an end face of an optical waveguide. The light source portion includes a circuit board having a mounting surface, and a light emitting device having a lead terminal to be connected to the mounting surface of the circuit board and emitting light in a direction parallel to the circuit board. The light emitting device is mounted on the circuit board in such a manner that a plate thickness of the circuit board falls within a range of a thickness of the light emitting device.

A light source portion for a backlight module that emits light to be incident on an end face of an optical waveguide, comprising:
- a circuit board having a mounting surface;
- and
- a light emitting device having a lead terminal to be connected to the mounting surface of the circuit board and emitting light in a direction parallel to the circuit board,
- wherein the light emitting device is mounted on the circuit board in such a manner that a plate thickness of the circuit board falls within a range of a thickness of the light emitting device.
A backlight module, comprising:
- an optical waveguide;
- and
- a light source portion that emits light to be incident on an end face of the optical waveguide,
- wherein the light source portion includes a circuit board having a mounting surface, and a light emitting device having a lead terminal to be connected to the mounting surface of the circuit board and emitting light in a direction parallel to the circuit board,
- the light emitting device being mounted on the circuit board in such a manner that a plate thickness of the circuit board falls within a range of a thickness of the light emitting device.
A connection structure of a backlight module for connecting a backlight module to a mounting circuit board, the backlight module including an optical waveguide and a light source portion that emits light to be incident on an end face of the optical waveguide, the mounting circuit board being electrically connectable to the light source portion, wherein:
- the light source portion includes a circuit board having an external connection terminal portion on a mounting surface placed to oppose the mounting circuit board, and a light emitting device that is mounted on the mounting surface of the circuit board and emits light in a direction parallel to the circuit board;
- and
- the mounting circuit board includes a feeding terminal, provided at a position opposing the external connection terminal portion on the mounting surface of the circuit board of the light source portion, for establishing an electrical connection with the external connection terminal portion through press-adhesion.
