Embodiment Construction

[0055] Reference figure 1 The structure of the image display device according to the embodiment of the present invention is described.

[0056] figure 1 It is an xz sectional view showing the image display device 100 according to the present embodiment.

[0057] The image display device 100 according to the present embodiment includes a front plate 101 and pixels 102 through which light can pass. The pixels 102 are provided on the rear surface of the front plate 101.

[0058] figure 1 A single pixel 102 is shown. A plurality of pixels each as a pixel 102 are arranged in the image display device 100.

[0059] Each pixel 102 is separated by a black matrix made of a medium having light absorption properties.

[0060] The front plate 101 is made of a medium transparent to visible light. For example, glass can be used.

[0061] The pixel 102 includes a light emitting layer 104, a fine structure layer 105, and an excitation unit (not shown). The fine structure layer 105 is provided betw...

Abstract

Provided is an image display apparatus in which color breakup of a reflection image formed from reflected ambient light may be reduced to suppress the influence of an ambient environment. The image display apparatus includes multiple pixels. Each of the pixels includes a light-emitting layer and a structure layer having a refractive index distribution in an in-plane direction parallel to a screen of the image display apparatus, for extracting light generated from the light-emitting layer. The structure layer includes multiple structures formed of a first medium and a layer formed of a second medium having a refractive index different from a refractive index of the first medium. The multiple structures are non-periodically arranged in the layer. Reflected ambient light is reflected by the multiple structures formed of the first medium to have an overlap range to reduce color breakup of a reflection image formed from the reflected ambient light.

Description

Technical field [0001] The present invention relates to an image display device and a manufacturing method suitable for the image display device. Background technique [0002] So far, image display devices with various structures have been proposed. Picture 14 It is a structural cross-sectional view showing an example of one of the known image display devices. [0003] in Picture 14 Here, the image display device 1400 includes a plurality of pixel structures each having a pixel 1402. [0004] In the image display device 1400, the pixels 1402 are provided on the inner surface side of the front plate 1401. The front plate 1401 is made of a medium transparent to visible light, such as glass or plastic. [0005] The pixel 1402 includes a light emitting layer 1403 and an excitation unit (not shown) for exciting the light emitting layer 1403. [0006] The excitation unit has, for example, a structure in which electron emission elements and electrodes are arranged on a substrate, and the ele...
