Mirror display, half mirror plate, and electronic device
First Claim
1. A mirror display comprising:
- a half mirror plate including a half mirror layer including at least one reflective polarizing plate, anda display device disposed behind the half mirror plate, whereinthe mirror display switches between a mirror mode in which the mirror display serves as a mirror without displaying any image of the display device and a display mode in which the mirror display device displays an image of the display device,the display device includes a display panel and a frame component that supports a peripheral portion of the display panel,the mirror display includes, only in the half mirror plate, a reflectance adjuster that makes equal the reflectance in a display region where the half mirror layer and the display panel face each other and the reflectance in a frame region where the half mirror layer and the frame component face each other,the reflectance adjuster includes (i) an additional reflective polarizing plate or an absorptive polarizing plate, (ii) a switching liquid crystal panel, and (iii) a component disposed at least in the frame region closer to the display device than the half mirror layer,the half mirror plate includes, in both the display region and the frame region, the additional reflective polarizing plate or the absorptive polarizing plate, the switching liquid crystal panel, and the at least one reflective polarizing plate in order from a front side to a back side,a transmission axis of the additional reflective polarizing plate or the absorptive polarizing plate and a transmission axis of the at least one reflective polarizing plate are substantially parallel or substantially perpendicular with each other, andthe switching liquid crystal panel is in a no-voltage-applied state in one of the mirror mode and the display mode, and is in a voltage-applied state in the other of the mirror mode and the display mode.

Abstract
The present invention provides a mirror display which prevents the boundary line between a frame region and a display region from being observed in a mirror mode and which thus has improved design quality. The mirror display of the present invention includes a half mirror plate including a half mirror layer, and a display device disposed behind the half mirror plate, the display device including a display panel and a frame component that supports a peripheral portion of the display panel, and the mirror display including a reflectance adjuster that makes equal the reflectance in a display region where the half mirror layer and the display panel face each other and the reflectance in a frame region where the half mirror layer and the frame component face each other.

1. A mirror display comprising:
-
a half mirror plate including a half mirror layer including at least one reflective polarizing plate, and a display device disposed behind the half mirror plate, wherein the mirror display switches between a mirror mode in which the mirror display serves as a mirror without displaying any image of the display device and a display mode in which the mirror display device displays an image of the display device, the display device includes a display panel and a frame component that supports a peripheral portion of the display panel, the mirror display includes, only in the half mirror plate, a reflectance adjuster that makes equal the reflectance in a display region where the half mirror layer and the display panel face each other and the reflectance in a frame region where the half mirror layer and the frame component face each other, the reflectance adjuster includes (i) an additional reflective polarizing plate or an absorptive polarizing plate, (ii) a switching liquid crystal panel, and (iii) a component disposed at least in the frame region closer to the display device than the half mirror layer, the half mirror plate includes, in both the display region and the frame region, the additional reflective polarizing plate or the absorptive polarizing plate, the switching liquid crystal panel, and the at least one reflective polarizing plate in order from a front side to a back side, a transmission axis of the additional reflective polarizing plate or the absorptive polarizing plate and a transmission axis of the at least one reflective polarizing plate are substantially parallel or substantially perpendicular with each other, and the switching liquid crystal panel is in a no-voltage-applied state in one of the mirror mode and the display mode, and is in a voltage-applied state in the other of the mirror mode and the display mode. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
