Title:
SURFACE LIGHT EMITTING DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2013/038802
Kind Code:
A1
Abstract:
In the present invention, a backlight chassis (14) of a back light (2) comprises a substrate mounting unit (14a) on which an LED substrate (12) is mounted and a diffuser plate support unit (14b) that is contiguous with the substrate mounting unit (14a) and that supports a diffuser plate (13) disposed on the light-output side of LEDs (11). In the backlight chassis (14), if a region having the greatest distance between the substrate mounting unit (14a) and the diffuser plate (13) is a first region (R1) and a region where this distance is less than in the first region (R1) is a second region (R2), a circuit board (16) is disposed in a space (T), which is a space formed on the side opposite the diffusion plate (13) across the substrate mounting unit (14a) and corresponds to the difference in height between the first region (R1) and the second region (R2), with a gap (S) between the circuit board and the substrate mounting unit (14a) in the second region (R2).
