る。DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the upper and lower substrates 1 and 2 on which the electrode patterns are formed have their peripheral portions sealed with a sealing material 3, and a liquid crystal 4 is sealed inside. The upper substrate 1
A metal film 5 having a matte property such as Cr 2 O 3 and a metal film 6 having a light shielding property such as Cr on the outer surface of
A three-layer metal film including a metal film 7 having a matte property such as Cr 2 O 3 is formed. Polarizing plates 8 are provided on the outer surface of the metal film 7 and the outer surface of the lower substrate 2, respectively.
9 are provided. The metal film 6 is formed to have a thickness of about 1000 Å in terms of light shielding property, and the metal films 5 and 7 are formed to have a thickness of about 500 Å in terms of matteness. The three-layer metal films 5, 6 and 7 are formed by vapor deposition or a sputtering method or the like to form a metal film pattern 10 having an effective display portion 10a, a symbol pattern 10b and the like as shown in FIG.

上する。Since the metal film 6 having a light shielding property is formed in this manner, unnecessary light leakage of the display section can be prevented.
Further, the metal film 5 having a matte surface on the upper and lower surfaces of the metal film 6,
Since 7 is formed, both surfaces of the metal film 6 are matte surfaces. Further, since the metal film pattern 10 is formed of the three-layer metal films 5, 6, and 7, the metal film pattern 10 can be formed into a fine pattern of several tens of μm by the etching method, and the positional accuracy is improved.

Further, the metal films 5 and 7 are formed on the upper and lower surfaces of the light-shielding metal film 6 so as to have a matte surface on both sides, but the metal film 5 or 7 is formed on only one surface to form a two-layer metal film, and there is no metal on one side. You may make it a glossy surface.

る。As is apparent from the above description, according to the present invention, the light-shielding film is formed by the multilayer metal film including the light-shielding metal film and the matte metal film. Both matteness can be satisfied. Further, it is possible to form a fine pattern and also improve the positional accuracy. As a result, excellent effects can be obtained when applied to a special field, for example, a liquid crystal display device for display in a viewfinder of a camera.
