Abstract

PURPOSE:To prevent unnecessary leakage of light by forming a light-shading film composed of multilayer metal films of a metal film capable of shading light and a metal film having no gloss. CONSTITUTION:The 3-layer metal films composed of the nonglossy metal film 5, the light-shading metal film 6, and the nonglossy metal film 7 are formed on the outer side of the upper base 1 sealing in liquid crystals 4 in the inside. Polarizing plates 8, 9 are formed on the outer side of the metal film 7 and the outer side of the lower base 2, respectively, thus permitting unnecessary light leakage from the display device to be prevented.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は液晶表示素子に係り、特に有効表示部における
不要な光もれを防ぐために基板に形成する遮光膜の構造
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a liquid crystal display element, and particularly to the structure of a light shielding film formed on a substrate to prevent unnecessary light leakage in an effective display area.

〔発明の背景〕[Background of the invention]

例工ば、カメラのファインダー内表示用などに用いる液
晶表示素子は、上基板または下基板に遮光膜を形成し、
有効表示部における不要な光もれを防止している（特開
昭５９−１５４４２４号）。For example, a liquid crystal display element used for display in the viewfinder of a camera, etc., has a light-shielding film formed on the upper or lower substrate.
This prevents unnecessary light leakage in the effective display area (Japanese Patent Laid-Open No. 154424/1983).

また前記遮光膜は、表示品質を高めるためｌこ、一般に
無光沢面となっている。Further, the light shielding film generally has a matte surface in order to improve display quality.

ーンを形成することができなく、また電極パターンとの
位置精度という点でも問題があり、カメラ用などの小屋
液晶表示に適用するには、パターン上の制約があった。Conventionally, the light-shielding film is formed by printing matte (matte) black ink. However, this method cannot form fine patterns, and there are also problems in terms of positional accuracy with the electrode pattern, and there are restrictions on the pattern when applying it to small LCD displays for cameras etc. .

〔発明の目的〕[Purpose of the invention]

本発明の目的は、微細パターンを形成することができる
と共に、電極パターンとの位置精度の向上が図れる遮光
膜を有する液晶表示素子を提供することにある。An object of the present invention is to provide a liquid crystal display element having a light-shielding film that can form a fine pattern and improve positional accuracy with respect to an electrode pattern.

本発明の他の目的は、不要な光もれを防ぐと共に、無光

素子を提供することにある。Another object of the present invention is to provide a liquid crystal display element having a light-shielding film that can prevent unnecessary light leakage and form a matte surface.

板８．９が設けられている。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, the upper and lower substrates 1.2 on which the electrode patterns are formed are sealed at their peripheries with a sealing material 3.
A liquid crystal 4 is sealed inside. The outer surface of the upper substrate 1 is coated with a metal film 5 having a matte property such as Cr, O, etc., a metal film 6 having a light-shielding property such as C', and a non-luster metal film 6 such as Cr2O3. A three-layer metal film consisting of a glossy metal film 7 is formed.Polarizing plates 8.9 are provided on the outer surface of the metal film 7 and on the outer surface of the lower substrate 2, respectively.

前記金属膜６は、遮光性という面から１００ＯＡ程度、

２図に示すように有効表示部１０ａ、シンボルパターン
１０ｂなどを有する金属膜パターン１０に形成する。The metal film 6 has a thickness of about 100 OA in terms of light shielding property.
The metal film 5.7 is formed to have a thickness of about 500 Å from the viewpoint of matteness. These three-layer metal films 5, 6, 7 are formed by vapor deposition or sputtering, and are formed into a metal film pattern 10 having an effective display area 10a, a symbol pattern 10b, etc., as shown in FIG.

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。Since the metal film 6 having a light-shielding property is thus formed, unnecessary light leakage from the display section can be prevented.

また金属膜６の上下面ｌこは無光沢面を有する金属膜５

度も向上する。Further, the upper and lower surfaces of the metal film 6 have matte surfaces.
．． 7, both surfaces of the metal film 6 become matte surfaces. Furthermore, since the metal film pattern 10 is composed of the three-layer metal film 5, 6, and 7, the metal film pattern 10 can be formed into a fine pattern of several tens of micrometers by an etching method, and the positional accuracy is improved.

．． 7 to form a matte surface on both sides, but it is also possible to form a two-layer metal film by forming the metal film 5 or 7 only on one side, so that one side has a matte surface.

Further, not only can a fine pattern be formed, but also the positional accuracy can be improved. Due to these, excellent effects can be obtained when applied to special fields, for example, liquid crystal display elements for display in camera viewfinders.
