因為位於各電極片上之相鄰隆突電極之間隔係約5微米 或更大，故相鄰隆突電極不會在持續電鍍期間彼此短路。 因此，形成隆突電極以使彼此完全絕緣。 若例如將電極片製成距形以使間距縮短，電極片之短邊 對正於對正方向，隆突電極以於各電極片上對正於與電極 片長軸平行之方向為佳。如此一來，隆突電極之總面積則 夠大而有效率。 此外，為了使相鄰電極片之間距更小，相鄰電極片可於 與電極片對正方向垂直之方向上交錯，而形成鋸齒狀排 列。此情況下，可裁切該隆突電極之邊角（故該隆突電極 之形狀係為五邊形、七邊形等），使隆突電極位於一電極 片上之經裁切邊角大體上平行於相鄰電極片之隆突電極之 經裁切邊角。是故，位置最接近之隆突電極之間距可長至 即使電極片間距縮短仍足以避免相鄰電極片間之短路，而 增加電路元件與液晶顯示面板間之電性連接的可信度。或 者，藉著提供經裁切邊角以取代電極片間距之縮短，可增 加各隆突電極之面積。 本發明因而可得到提供一種液晶顯示裝置之優點，其中 電路元件之電極片與液晶顯示面板之結合片之間不會有電 性連接損壞之情況。 熟習此技藝者可於參照附圖閱讀並明瞭以下詳述下明白 本發明之此項及其他優點。 -9- 本紙張尺度適用中國國家標準(CNS) A4規格(210X297公釐)
