A liquid crystal display device includes LEDs, a liquid crystal panel 11, a chassis, a frame 13, positioning ribs 23, and step portions 30. The liquid crystal panel 11 is configured to display using light from the LEDs. The chassis is arranged on an opposite side of the liquid crystal panel 11 from a display surface that is for display. The frame 13 is arranged on the display surface side of the liquid crystal panel 11. The frame 13 holds at least the liquid crystal panel 11 and the LEDs with the chassis such that the liquid crystal panel 11 and the LEDs are sandwiched between the frame 13 and the chassis. The positioning rib 23 having a block-like shape projects from the frame 13 toward the chassis and includes a peripheral surface opposite a peripheral surface of the liquid crystal panel 11 for positioning the liquid crystal panel 11 relative to the display surface direction. The step portion 30 projects from a portion of a distal end surface of the positioning rib 23 toward the chassis so as to form a step. The step portion 30 includes a peripheral surface (the inner surface 30a) opposite the peripheral surface of the liquid crystal panel 11. The peripheral surface of the step portion 30 is on the same plane with the peripheral surface of the positioning rib 23 (the inner surface 23a) which is opposite the peripheral surface of the liquid crystal panel 11.
