Problems solved by technology

[0005] and, whether in Figure 8 and Figure 11 In any of the cases shown, a backlash force is generated in the FPC board 116 that is bent due to being rolled up, and because of this, the position of the LED 131 with respect to the side surface (light receiving surface) 132S of the light guide plate 132 is easily changed from the desired position. The position deviation of (in a word, the position accuracy of LED 131 is easy to reduce)
[0006] In addition, the positional deviation of the LED (light source) 131 relative to the side surface 132S of the light guide plate 132 becomes a cause of uneven light quantity in the light from the backlight unit 139, and further, causes a decrease in the display quality of the liquid crystal display device 169. a reason

Abstract

An LED (31) is mounted on an active matrix substrate (11), and a light-emitting surface (31L) of the LED (31) is on the outer substrate surface (11T) side of the active matrix substrate (11).

Description

technical field [0001] The present invention is a liquid crystal display device. Background technique [0002] Recently, thin display devices have gradually become mainstream. As an example of such a display device, there are Figure 8 ~ Figure 10 The liquid crystal display device 169 is shown. Figure 9 It is an exploded perspective view of the liquid crystal display device 169 . Figure 10 Yes Figure 9 A plan view of the liquid crystal display panel 119 and the like included in the illustrated liquid crystal display device 169, Figure 8 Yes Figure 9 A cross-sectional view of the illustrated liquid crystal display device 169 indicated by an arrow on line E-E'. [0003] like Figure 8 and Figure 9 As shown, the liquid crystal display device 169 includes a liquid crystal display panel 119 and a backlight unit 139 that irradiates light to the liquid crystal display panel 119 . and, if Figure 7 ~ Figure 9 As shown, the FPC (Flexible Printed Circuits: flexible prin...
