A window glass for an automobile, wherein a surface of a single sheet of glass is provided with a dark-colored film, or wherein a window glass laminated with at least a single sheet of glass and at least a single sheet of a synthetic resin film is provided with the dark-colored film on a surface of the window glass or on an interface between the glass and the synthetic resin film characterized by that a first visible light transmittance of an emitted light transmitting portion of the window glass through which a light of an alarm lamp substantially transmits is larger than a second visible light transmittance of a dark-colored portion of the window glass formed with the dark-colored film.

An electrically heatable windshield comprises two glass plates bonded to each other with an interlayer therebetween and a transparent conductive layer formed at contacting surface between one of the glass plates and the interlayer so that the windshield is heated by supplying a current to the transparent conductive layer through a bus bar for feeding power. A colored layer such as a ceramic color print is formed at the peripheral portion of the surface, in contact with the interlayer, of at least one of the glass plates. The bus bar is formed on the colored layer without expanding. A transparent protective layer is formed so as to cover the edge portion of the colored layer which is near the center of the glass plates, and the transparent conductive layer is formed over the transparent protective layer.

A method for fabrication of an electrochromic device having perfect tight closure of the cell, wherein two or more banks constituting an external frame for the substrates are formed with use of a sealing material at the peripheral positions on the surface of the first or second substrate where the electrode has been formed; then a gel-like electrolytic solution is placed on the surface of the first substrate; thereafter the second substrate is disposed with the surface side thereof where the electrode has been formed being opposed to the surface side of the first substrate where the electrode has been formed; and finally both first and second substrates are laid one on the other to be contact-bonded, and wherein the two or more banks are composed of one or more cured inner bank and an uncured outer bank; when the uncured outer bank is in the two-stage structure having a height taller than that of the inner bank, and is of such two-stage structure composed of a cured bank having a height shorter than that of the inner bank and an uncured bank laminated on the cured bank, such inner bank is provided one or more in number; and when the uncured outer bank is in a single stage structure, the inner bank is provided two or more in number with a space interval being provided between them, both first and second substrates being joined together by the contact-bonding.
