Problems solved by technology

[0005] However, the size of the porous particles described in Patent Document 1 has a minimum diameter of several μm, and since the porous particles become a source of diffusion of incident visible light, the haze (turbidity) increases, making it unsuitable for display devices requiring high transparency.

Embodiment 1

[0070] figure 1 (a) shows the cross-sectional structure of the display device of the first embodiment. The liquid crystal panel 31 has image 3 In the illustrated configuration, a capacitive touch panel 34 is arranged on the output side of the liquid crystal panel 31 through the gas layer AL. AR films 32 and 33 are attached to the interface between the liquid crystal panel 31 and the gas layer AL, and the interface between the touch panel 34 and the gas layer AL, respectively. This suppresses the reflection of light at the interface between the liquid crystal panel 31 and the gas layer AL, and between the touch panel 34 and the gas layer AL and the interface.

[0071] A linear polarizing layer 35 is laminated on the touch panel 34 . A base material layer 37 is laminated on the linearly polarizing layer 35 via an adhesive layer 36 . In Example 1, the adhesive layer 36 is made of a polarization-eliminating adhesive containing a polarization-eliminating fiber, and the substra...

Embodiment 2

[0074] figure 1(b) shows the cross-sectional structure of the display device of the second embodiment. In Example 2, the adhesive layer 39 is made of an acrylic adhesive that does not contain polarization-eliminating fibers, and the substrate layer 40 is made of a polarization-eliminating substrate that includes polarization-eliminating fibers. Other aspects and figure 1 (a) is the same, and the explanation is omitted.

Embodiment 3

[0076] figure 1 (c) shows the cross-sectional structure of the display device of the third embodiment. In Example 3, the adhesive layer 36 is composed of a polarization-eliminating adhesive containing polarization-eliminating fibers, and the substrate layer 40 is composed of a polarization-eliminating substrate containing polarization-eliminating fibers. That is, both the base material layer 40 and the adhesive layer 36 contain polarization-eliminating fibers. Other aspects and figure 1 (a) is the same, and the explanation is omitted.

Abstract

This display apparatus has: a liquid crystal panel (31); a touch panel (34) disposed on the liquid crystal panel (31); a base material layer (37, 40) laminated on the touch panel (34); and an adhesive layer (36, 39) disposed between the touch panel (34) and the base material layer (37, 40). The base material layer (37, 40) and / or the adhesive layer (36, 39) contains a fiber having characteristics of eliminating polarization.

Description

technical field [0001] The present invention relates to a display device having a liquid crystal panel, a display device for an automobile, and a method for manufacturing the display device. Background technique [0002] Since the liquid crystal panel has a structure in which liquid crystal is filled in the gap between two sheets of glass and a polarizing plate is arranged outside the glass, in principle, the display image displayed on the liquid crystal panel generates linearly polarized light. The linearly polarized display image is observed through the light-shielding mirror with the function of polarized light. When the polarization direction of the light-shielding mirror is perpendicular to the polarization direction of the display image, the amount of light transmitted through the light-shielding mirror is greatly reduced, and the viewing angle of the displayed image Recognition is significantly reduced. [0003] As a technique for canceling polarized light in a displ...
