位置精度という点でも問題があり、カメラ用などの小型
液晶表示に適用するには、パターン上の制約があつた。Conventionally, the light shielding film is formed by printing a matte (matte) black ink. However, this method cannot form a fine pattern and has a problem in terms of positional accuracy with respect to the electrode pattern. Therefore, there are restrictions on the pattern when it is applied to a small liquid crystal display for a camera or the like. .

０ｂなどを有する金属膜パターン１０に形成する。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, and the second
As shown in the figure, the effective display portion 10a, the symbol pattern 1
The metal film pattern 10 having 0b or the like is formed.
このように、遮光性を有する金属膜６を形成してなるの
で、表示部の不要な光もれを防止できる。また金属膜６

面にしてもよい。Although the metal films 5, 6 and 7 are formed on the outer surface of the upper substrate 1 in the above embodiment, they may be formed on the outer surface of the lower substrate 2. Further, the metal film 5 is formed on the upper and lower surfaces of the light-shielding metal film 6,
7 is formed to be a matte surface on both sides, but the metal film 5 or 7 may be formed on only one surface to form a two-layer metal film, which is a matte surface on one side.
