Embodiment approach 1
[0064] use Figure 1 to Figure 6 Embodiment 1 of the present invention will be described.
[0065] First, the configuration of a television receiver TV including a liquid crystal display device 10 will be described.
[0066] like figure 1 As shown, the television receiver TV of the present embodiment is configured to include: a liquid crystal display device 10; two front and back cabinets Ca, Cb housed in a manner sandwiching the liquid crystal display device 10; a power supply P; a tuner T; . The liquid crystal display device (display device) 10 has a horizontally long square shape as a whole, and is housed in a vertical state. like figure 2 As shown, this liquid crystal display device 10 includes a liquid crystal panel 11 as a display panel and a backlight device (illumination device) 12 as an external light source, and these are integrally held by a frame-shaped outer frame 13 or the like.
[0067] Next, the liquid crystal panel 11 and the backlight unit 12 constitut...
Embodiment approach 2
[0103] Next, use Figure 9 to Figure 11 Embodiment 2 of the present invention will be described.
[0104] In the liquid crystal display device 10 included in the television receiver TV of the second embodiment, the backlight unit 12 to the diffusion lens 24 of the first embodiment are omitted, and the rest is the same as that of the first embodiment. The same reference numerals are assigned to the same parts as those in Embodiment 1 described above, and overlapping descriptions will be omitted.
[0105] The backlight device 12 adopted in Embodiment 2 has LED light sources 80 on the LED substrate 81, so that a light source high-density region with relatively close arrangement intervals of the LED light sources 80 is formed at the central portion of the LED substrate 81 (that is, the central portion of the chassis 14). LH is arranged on the LED substrate 81 in such a manner that the light source low-density region LL in which the LED light sources 80 are arranged at a relativel...
