The purpose of the present invention is to eliminate or suppress luminance non-uniformity of the display surface without increasing the number of light sources in an illuminating device. A backlight device of the present invention is provided with: an LED light source (28), which has light distribution wherein light having a peak emission intensity travels in the tilted direction with respect to the front direction; a chassis (22) which houses the LED light source (28), and which is opened to the light outputting side; a reflection member (26), which has a plurality of tilted surfaces (26a) that are tilted from the surface where the LED light source (28) is disposed to the side where the chassis (22) is opened, and which directs the light emitted from the LED light source (28) to the front direction of the LED light source (28) by means of the tilted surface (26a); and a diffuser panel (20), which is provided on the side where the chassis (22) is opened, and has a light blocking pattern (25) printed on the surface that faces the LED light source (28).
