Embodiment Construction

[0016] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numbers refer to like elements throughout. Certain layers and regions may be exaggerated for clarity.

[0017] It will be understood that when an element is referred to as being "on" or "under" another element, it can be directly on and on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being "directly on" or "directly under" another element, there are no intervening elements present. As used herein, the term "and / or" i...

Abstract

An optical sheet includes a reflective polarizer and a filter layer. The reflective polarizer reflects a part of incident light and transmits another part of the incident light. The filter layer selectively reflects the transmitted light passed through the reflective polarizer. The filter layer reflects at least one of a first wave band that is an overlapped area between a green peak and a blue peak in the spectrum of incident light, and a second wave band that is an overlapped area between a green peak and a red peak in the spectrum of incident light.

Description

technical field [0001] The invention relates to an optical sheet and a display with the optical sheet. Background technique [0002] A liquid crystal display (LCD) is one of displays using liquid crystals. Compared with other displays, LCDs have advantages such as thinness, lightness, utilization of low driving voltage, and low power consumption, so that LCDs are widely used in industries. [0003] A conventional LCD requires a liquid crystal panel and a CCFL (Cold Cathode Fluorescent Lamp) lamp that supplies light to the liquid crystal panel, and the liquid crystal panel has a color filter to realize colors. [0004] When white light from a lamp is transmitted through a color filter, the spectrum of the light has three peaks corresponding to colored light such as red, green and blue. However, except for the relatively middle region of the peak, the spectra of each color overlap with each other. [0005] Therefore, except for the middle region of each color peak, the side...
