Problems solved by technology

[0004] However, since the images displayed on the liquid crystal display panel comprehensively present linearly polarized images along the A1 direction, as shown in screen F1, when the observer watches the liquid crystal display for a long time, it is easy because the polarization characteristics of the images are the same linear polarization visual fatigue

Embodiment Construction

[0039] figure 2 A schematic diagram of a display device integrated with optical sheets is shown according to an embodiment of the present invention. Please refer to figure 2 , the display device 200 includes a display panel 210 and an optical sheet 220, and the display panel 210 is suitable for emitting a linearly polarized light L1 with a polarization direction A1. Specifically, in this embodiment, the display panel 210 is mainly composed of a pixel array 212 and a polarizer 214 located between the pixel array 212 and the optical sheet 220, wherein the polarizer 214 has a transmission axis A1, After the image displayed on the display panel 210 passes through the polarizer 214, a linearly polarized image with a polarization direction tending to A1 is output. In particular, the optical sheet 220 has a phase retardation film 222, and the phase retardation film 222 has a plurality of optical axes A2 with different extension directions, wherein the optical axes A2 with differe...

Abstract

The invention relates to an optical sheet which is suitable for linearly polarized light to pass through and comprises a substrate and a phase delay film, wherein the phase delay film is positioned on the substrate and comprises a plurality of optical axes with different extension directions; the linearly polarized light is changed into linearly polarized light with many different polarization directions after passing through the phase delay film; and the phase delay film has a phase delay quantity of lambda / 2 in any place of an area where the linearly polarized light passes through, and lambda is the wavelength of the linearly polarized light. Thus, the optical sheet of the invention can change the single polarization direction of the linearly polarized light into different polarization directions. In addition, the invention also provides a display device, a production method of the optical sheet and a production method of the display device.

Description

technical field [0001] The present invention relates to an optical sheet, a display device and a manufacturing method thereof, and in particular to an optical sheet capable of providing different linear polarization directions for different regions passing through the optical sheet, a display device and a manufacturing method thereof. Background technique [0002] With the advancement of display technology, people can make their lives more convenient with the assistance of display devices, among which flat panel displays (Flat Panel Display, FPD) have become the mainstream of current displays due to their light weight and thin size. Among many flat-panel displays, liquid crystal displays (LCDs) are popular among consumers because of their superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. [0003] figure 1 A schematic cross-sectional view of a conventional liquid crystal display is s...
