Abstract

An electronic device such as a portable phone has a casing, a display element provided in the casing, and a panel attached to the casing to cover the display element. A half mirror layer and a shading layer are formed on the panel. An opening of the shading layer is above the display element. The surface of the panel is seen in a substantially continuously uniform color when no electricity is supplied to the display element, and a display produced by the display element can be seen through the panel when electricity is supplied to the display element.

Claims

1. An electronic device, comprising:

a casing;

an electronic component disposed within the casing;

a first display element disposed within the casing; and

a cover covering at least a portion of the casing where the first display element and the electronic component as a second display element are disposed therein, wherein a half mirror layer is formed on an outer surface of the cover, and the half mirror layer reflects light having a predetermined wavelength and transmits light having a wavelength other than the predetermined wavelength, a shading layer is formed on an inner surface of the cover that is opposite the half mirror portion, and a first opening and a second opening are formed in portions of the shading layer where the first display element and the second display element are disposed thereunder, respectively, and a diffusion layer is formed on the second opening.

2. The electronic device according to claim 1, wherein:

a panel is disposed on the first display element, wherein the panel is configured to absorb light entered into the electronic device through the cover.

3. The electronic device according to claim 1, wherein:

a wavelength of light that is reflected by the half mirror layer is different from a wavelength of light that is emitted from the first display element.
