Abstract

It is provided an electro-optical device including an electro-optical panel having a display area on which light from a light source is incident and an optical thin film disposed on the electro-optical panel at the side on which the light is incident and covering at least a portion of the display area. The optical thin film transmits at least a light component in a first wavelength range of the light from the light source and reflects at least a light component in a second wavelength range, wavelength in the second wavelength range being longer than wavelength in the first wavelength range.

Claims (20)

1. An electro-optical device comprising:

an electro-optical panel including a display area on which light from a light source is incident; and

an optical thin film disposed on the electro-optical panel at a side on which the light is incident and covering at least a portion of the display area, wherein

the optical thin film transmits at least a light component in a first wavelength range of the light from the light source and reflects at least a light component in a second wavelength range, the wavelength in the second wavelength range being longer than the wavelength in the first wavelength range, wherein the optical thin film is a lamination film composed of alternately laminated zirconium oxide and silicon oxide films.

2. An electro-optical device comprising:

an electro-optical panel including a display area on which light from a light source is incident; and

an optical thin film disposed on the electro-optical panel at a side on which the light is incident and covering at least a portion of the display area, wherein

the optical thin film transmits at least a light component in a first wavelength range of the light from the light source and reflects at least a light component in a second wavelength range, the wavelength in the second wavelength range being longer than the wavelength in the first wavelength range, wherein the optical thin film is a lamination film composed of alternately laminated niobium oxide and silicon oxide films.

3. An electro-optical device comprising:

an electro-optical panel including a display area on which light from a light source is incident; and

an optical thin film disposed on the electro-optical panel at a side on which the light is incident and covering at least a portion of the display area, wherein

the optical thin film transmits at least a light component in a first wavelength range of the light from the light source and reflects at least a light component in a second wavelength range, the wavelength in the second wavelength range being longer than the wavelength in the first wavelength range, wherein

the electro-optical panel includes a pair of substrates having an electro-optical material therebetween; and

the optical thin film is disposed on a surface of one of the pair of substrates, wherein the one of the pair of substrates is at the side on which light from the light source is incident and the surface on which the optical thin film is disposed is at the side on which light from the light source is incident.

4. An electro-optical device comprising:

an electro-optical panel including a display area on which light from a light source is incident; and

an optical thin film disposed on the electro-optical panel at a side on which the light is incident and covering at least a portion of the display area, wherein

the optical thin film transmits at least a light component in a first wavelength range of the light from the light source and reflects at least a light component in a second wavelength range, the wavelength in the second wavelength range being longer than the wavelength in the first wavelength range, wherein

the electro-optical panel includes a pair of substrates having an electro-optical material therebetween and a pair of dust-proof substrates disposed on the pair of substrates, respectively, at sides not opposing the electro-optical material; and

the optical thin film is disposed on a surface of one of the pair of dustproof substrates, wherein the one of the pair of dust-proof substrates is at the side on which light from the light source is incident and the surface on which the optical thin film is disposed is at the side on which light from the light source is incident.
