    • A liquid crystal display device includes a liquid crystal display element having a liquid crystal layer sandwiched between a pair of upper and lower substrates, a flexible circuit board disposed around a periphery of the liquid crystal display element, an illuminating light source having a line light source, a light guide and a reflector and disposed behind the liquid crystal display element, a metal upper case having a sidewall bent back and a display window, a resin lower case for housing the illuminating light source. The upper and lower cases are clamped by crimping plural nails formed in the sidewall of the upper case at an outer surface of the lower case after stacking the liquid crystal display element, the flexible circuit board and the illuminating light source between the upper and lower cases. An electrical connection between the upper case and a grounding pattern formed on the flexible circuit board is made by at least one component in chip form having a conductive region and being attached to a portion of the grounding pattern bent over the lower substrate, and a metal tape having one end thereof being interposed between opposing portions of the upper and lower cases which are pressed against each other and the other end thereof being positioned to be pressed against the conductive region of the at least one component.
    • 液晶显示装置包括液晶显示元件,液晶显示元件具有夹在一对上下基板之间的液晶层,设置在液晶显示元件周围的柔性电路板,具有线光源的照明光源 配置在液晶显示元件后面的具有侧壁弯曲的金属上壳体和显示窗,用于容纳照明光源的树脂下壳体。 在将液晶显示元件,柔性电路板和照明光源堆叠在上壳体和下壳体之间的情况下,通过在下壳体的外表面压接形成在上壳体的侧壁中的多个钉子来夹紧上壳体和下壳体 。 上壳体和形成在柔性电路板上的接地图案之间的电连接是由具有导电区域的至少一个片状元件制成的,并且被附接到在下基板上弯曲的接地图案的一部分,金属 胶带,其一端插入在彼此压靠的上壳体和下壳体的相对部分之间,其另一端定位成压靠至少一个部件的导电区域。
