Grating sheet, LCD device and methods for manufacturing grating sheet and LCD panel

摘要

A grating sheet, a LCD device and methods for manufacturing the grating sheet and a liquid crystal display panel are provided. The grating sheet comprises a plurality of primary color gratings in parallel, each of which comprises a red R sub-grating, a green G sub-grating and a blue B sub-grating in parallel, and each sub-grating comprises an opening area and a reflective region disposed around the opening area and corresponds to a pixel unit on a sub-array substrate. The grating sheet, the liquid crystal display panel and methods for manufacturing the grating sheet and a liquid crystal display panel may be applicable to a system with a liquid crystal display.

1. A grating sheet comprising a plurality of primary color gratings disposed parallel with one another,
wherein each primary color grating comprises a red (R) sub-grating, a green (G) sub-grating, and a blue (B) sub-grating parallel with one another, and wherein each sub-grating comprises:
a lower metal layer disposed in an opening area for diffraction therein; andan upper metal layer disposed in a reflective region around the opening area;wherein a reflective film overlays the upper metal layer and is configured for reflecting light emitted from a backlight module but blocked by the grating sheet back to the backlight module, andthe upper metal layer and the lower metal layer are the same material, and the each sub-grating corresponds to a pixel unit.
