Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] figure 1 It is a plan view showing a liquid crystal display device according to an embodiment of the present invention. figure 2 yes means figure 1 A diagram of the back side of the LCD device is shown. image 3 Yes figure 1 The III-III line sectional view of the liquid crystal display device shown.

[0026] The liquid crystal display device has a liquid crystal display panel 10 . The liquid crystal display panel 10 has a display surface 12 for displaying images and a back surface 14 opposite to the display surface 12 (refer to image 3 ). The liquid crystal display panel 10 has a pair of substrates 16 and 18 (both are glass substrates), and a liquid crystal (not shown) is sandwiched between them. One substrate 16 is a TFT (Thin Film Transistor, thin film transistor) substrate (or an array substrate) including thin film transistors, pixel electrodes, wiri...

Abstract

A liquid crystal display device includes: a liquid crystal display panel 10 having a display surface 12 and a rear surface 14; a light guide plate 52 arranged so as to avoid a position below an edge of the liquid crystal display panel on the side of the rear surface; a flexible wiring board 26 having a portion 44, 50 arranged below the edge of the liquid crystal display panel 10 with a gap disposed between the portion and the edge; a light source 58 mounted, for introducing light, on a surface of the flexible wiring board 50 on the side of the liquid crystal display panel at a position below the edge of the liquid crystal display panel; and a reinforcing plate 62 located next to the light source on the opposite side to the light guide plate and attached to the surface of the flexible wiring board where the light source is mounted.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] As a liquid crystal display device having a backlight, an example using an FPC (Flexible Printed Circuits) on which LEDs (Light Emitting Diodes, light emitting diodes) are mounted is known. In the example shown in Patent Document 1, the FPC is bent so as to extend from the liquid crystal display panel to the rear side of the light guide plate of the backlight. The LED mounted on the FPC is arranged facing the end surface of the light guide plate. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-216753 [0004] The base material of FPC is made of thin and flexible material, so the wiring is easily damaged when bending stress is generated. Therefore, it is considered to paste the reinforcement board on the FPC. However, if the reinforcing plate is attached, the thickness of the FPC will increase, so it will be difficult to meet the demand for device ...
