    摘要： A liquid crystal display device (100) of the present invention includes an edge light type backlight unit (10) and a liquid crystal panel (20). The backlight unit (10) includes a light guide plate (2) and a light source (1) that emits light to a light entrance end surface (2a) of the light guide plate (2). An opposite end surface (2b), of the light guide plate (2), which is opposite to the light entrance end surface (2a), is shaped to have one or more triangular shape(s) or one or more rounded shape(s) in a cross section both in a thickness direction of the light guide plate (2) and in a peak luminance direction of light from the light source (1). Light parallel to the peak luminance direction, which light is from the light source (1), is suitably reflected without being scattered by an inclined surface of the opposite end surface (2b).

    摘要： A backlight unit (20) includes: light sources (4A, 4B); light guide members (2A, 2B), the light source (4A) being provided to a side surface of the light guide member (2A), the light source (4B) being provided to a side surface of the light guide member (2B), the light sources (4A, 4B) being provided across the light guide members (2A, 2b) in plane view; and an optical path changing member (1) for changing an optical path of light passing through the optical path changing member, the optical path changing member (1) having a light incidence surface (SUF1) for receiving light emitted directly from the light guide member (2A or 2B), and a light exit surface (SUF2) for emitting, directly to a display panel outside of the backlight unit (20), the light thus received via the light incidence surface (SUF1). This configuration makes it possible to large-size a backlight unit without the fear of display quality deterioration, and makes it possible for such a backlight unit to emit light with luminance directivity in different directions.

    摘要： A planar illumination device has a light source that shines light into a light guide plate through one side face (i) thereof and a reflector member laid on the back face of the light guide plate opposite to the light emission face thereof. In the vicinity of another side face (ii) of the light guide plate opposite to the side face (i) thereof through which the light is shone into the light guide plate, a slit is formed so as to extend along that side face (ii). A portion of the reflector member is, by being bent into an L shape, formed into an insertion portion, and this insertion portion is inserted into the slit.
