Claim:
A backlight device for a liquid crystal module, the backlight device comprising: a frame; a linear light source configured to emit light; and a lamp holder supporting the linear light source relative to the frame, the lamp holder including an arc-shaped arm component that has a middle portion and a pair of end portions with an opening therebetween, the end portions extending from the middle portion, respectively, a concave protrusion that extends from the middle portion of the arm component in a radial inward direction of the arm component, the concave protrusion having an outward concave face that contacts an outer peripheral face of the linear light source, and a pair of convex protrusions that extends from the end portions of the arm component in the radial inward direction of the arm component, respectively, each of the convex protrusions having an inward convex face that contacts the outer peripheral face of the linear light source at a radial innermost position of the inward convex face such that the convex protrusions press the linear light source against the concave protrusion.
