IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/147268
Kind Code:
A1
Abstract:
An image display device (10) that comprises: a display panel (102); a lower frame (111) that includes a flat part (111A) and a side wall part (111B); light sources (113) that are arrayed on the flat part (111A); support pins (112) that are arrayed on the flat part (111A) so as to be separated from the light sources (113); a diffusion plate (106) that diffuses light emitted by the light sources (113) and emits the light toward the display panel (102); and a brightness regulation plate (107) that is supported in the middle of the support pins (112) between the diffusion plate (106) and the lower frame (111), that has an outer edge that substantially coincides with an outer edge of an effective area of the display panel (102), and that transmits a portion of the light emitted by the light sources (113) to the side on which the diffusion plate (106) is arranged. Between the diffusion plate (106) and the side wall part (111B), the brightness regulation plate (107) curves toward the side wall part (111B) so as to gradually approach the lower frame (111) from an outer edge of the flat part (111A) to an outer edge of the side wall part (111B).
