Patterned retarder, manufacturing method thereof, and display device

Abstract

An embodiment of the invention provides an imaging delayer, a production method thereof and a display device and relates to the technical field of display. The imaging delayer comprises an imaging delaying layer, a phosphor layer formed on the imaging delaying layer and a color film formed on the phosphor layer, wherein single primary color light rays which enter the phosphor layer are transformed into the white light and ejected through the color film. According to the delayer, the method and the device, the problem that white light mixed by light rays in different light rays generates different phase delay when passing through a display panel and the imaging delayer is solved, and the vertical stereo display visual angle of the display device is improved simultaneously.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a patterned retarder, a manufacturing method thereof, and a display device. Background technique [0002] With the gradual maturity of liquid crystal display technology, people's demand for liquid crystal displays has gradually transitioned from a simple flat liquid crystal display to a three-dimensional liquid crystal display. The realization principle of the three-dimensional picture is to let the left and right eyes see pictures from different angles, thereby generating a three-dimensional image in the mind. [0003] The current mainstream three-dimensional liquid crystal display technology is mainly divided into shutter type three-dimensional liquid crystal display technology and polarized light type three-dimensional liquid crystal display technology. The shutter-type three-dimensional liquid crystal display technology is to form two sets of pictures corresponding to the l...

Problems solved by technology

[0004] However, the white light usually used in traditional polarized 3D liquid crystal displays is mixed with light of different wavelengths, so that the phase delay will occur when the light passes through the liquid crystal layer and the patterned retarder, which will affect the display effect of the 3D image.

At the same time, because the glass substrate and polarizer between the color filter substrate and the image retarder of the traditional polarized three-dimensional liquid crystal display are thicker, in order to avoid crosstalk, the viewing angle will be limited when the light enters the patterned retardation layer, which will cause the polarization of the polarized three-dimensional liquid crystal. The viewing angle of the display is small
