LED BACKLIGHT DEVICE AND LED IMAGE DISPLAY DEVICE

PROBLEM TO BE SOLVED: To provide an LED backlight device in which a spacer is hardly broken and which can suppress positional deviation of a first optical sheet and a second optical sheet, and to provide an LED display device.SOLUTION: An LED backlight device 20 includes: an LED mounting substrate including a plurality of LED elements 42 mounted on one surface 41A of a wiring board 41; a first optical sheet 50 arranged so as to oppose to the LED elements 42; a second optical sheet 60 arranged on a light emission side of it; and a spacer including a first spacer part 71 for separating the first optical sheet 50 with respect to the LED mounting substrate, and a frame-like second spacer part 72 for surrounding an outer peripheral surface 50A of the first optical sheet 50, and for separating the second optical sheet 60 with respect to the first optical sheet 50. The first spacer part 71 is located on the inner side of the second spacer part 72, and the first spacer part 71 is provided integrally with the second spacer part 72.SELECTED DRAWING: Figure 3 【課題】スペーサが破損しにくく、第１の光学シートおよび第２の光学シートの位置ずれを抑制できるＬＥＤバックライト装置およびＬＥＤ表示装置を提供する。【解決手段】ＬＥＤバックライト装置２０は、配線基板４１の一方の面４１Ａに実装された複数のＬＥＤ素子４２を備えるＬＥＤ実装基板と、ＬＥＤ素子４２と対向するように配置された第１の光学シート５０と、その光出射側に配置された第２の光学シート６０と、ＬＥＤ実装基板に対し第１の光学シート５０を離間させる第１のスペーサ部７１、および第１の光学シート５０の外周面５０Ａを取り囲み、かつ第１の光学シート５０に対し第２の光学シート６０を離間させる枠状の第２のスペーサ部７２とを有するスペーサと、を備える。第１のスペーサ部７１が、第２のスペーサ部７２の内側に位置し、かつ、第１のスペーサ部７１が第２のスペーサ部７２と一体的に設けられている。【選択図】図３
