A surface light source device includes a light source; a light guide plate that has a light entrance surface through which light enters, and that emits the light entering through the light entrance surface from a light exit surface; a wiring board; and a metal frame. The metal frame includes a bottom portion having a bottom surface that faces a surface on an opposite side to the light exit surface, a side wall erected on an outer periphery of the bottom surface, and a projecting portion provided on the side wall so as to project toward the bottom surface side. The metal frame houses the light source, the light guide plate, and the wiring board. At least a part of the light source is disposed between the bottom portion and the projecting portion, and the wiring board is disposed between the light source and the bottom portion.

Surface light source device, display device, and electronic device

A lens array capable of effectively converging light entering from a light source and constituting a liquid crystal device of a high contrast includes liquid crystal of a twisted nematic type sandwiched between a TFT substrate and a counter substrate. A micro lens array is formed in the counter substrate. Lenses constituting the micro lens array respectively have a shape of a rotational aspheric surface, and an optical center axis F thereof is tilted in a bright vision direction of the liquid crystal.
