Description
此申請案主張2015年10月6日在韓國智慧財產辦公室提出申請的韓國專利申請案第10-2015-0140574號之優先權和權利，茲將該案全文以引用方式納入本文中。
本發明係關於顯示裝置。
通常，晶格型黑圖案，其被稱為黑矩陣，配置於濾色器的彩色像素之間以改良對比性。已知的黑矩陣中，使用藉由將作為顏料的鉻(Cr)澱積在整體玻璃基板上並蝕刻該玻璃基板以形成圖案的方法，但方法中須要高成本，且有鉻的高反射性的問題及因為形成鉻廢液而造成環境污染的問題。
因此，積極進行提供黑矩陣之精細方法之研究，亦進行製備黑色組成物作為碳黑以外的著色顏料之研究，但碳黑以外的著色顏料的遮光性弱，因此須極度提高所混合之著色顏料的量，結果，有著組成物黏度提高的問
題，造成難以處理著色顏料，或者所形成的層的強度或對於基板的黏著性顯著降低。
此外，隨著顯示裝置螢幕尺寸的提高，發生亮度問題，使得所得的背光較亮。由於背光的亮度提高，相較於已知的黑矩陣，此黑矩陣須具有較高的遮光性。
本說明書係關於顯示裝置，其包括黑矩陣，該黑矩陣能夠有效地控制在非像素區中的眩光現象。
本說明書的一個例示具體實施例提出一種顯示裝置，其包括：基板，包括像素區和非像素區；黑矩陣，配置於基板的非像素區的至少一部分；和配置於基板的像素區中之像素電極及對應於像素電極的共同電極，其中像素區被配置於基板上同時彼此交錯的複數個閘極線和複數個數據線所分隔，非像素區包括含括薄膜電晶體、閘極線和數據線的佈線單元，且黑矩陣符合以下式1之0.004或更高且0.22或更低的值。
式1中，k是指黑矩陣的消光係數，t是指黑矩陣的厚度，和λ是指光的波長。
根據本說明書之顯示裝置，藉由非像素區中的佈線單元控制光反射率，能夠得到具有高影像品質之顯示器。

本說明書中，除非明確與所述者相矛盾，否則當描述特定部分“包含”特定建構元件時，意謂可以另含括另一建構元件，並非排除另一建構元件。
下文中，將更詳細地描述本說明書。
本說明書中，顯示裝置是TV、電腦螢幕之類的統稱，並包括形成影像的顯示裝置及承載該顯示裝置的機殼。
本發明者開發顯示裝置，其將被述於下文中，此為用以得到黑矩陣的性能及使得黑矩陣能夠精細圖案化以防止光反射、在非像素區的漏光現象等之重複研究的結果。特別地，本發明者發現當黑矩陣符合以下的式1時，黑矩陣展現極佳之光反射降低的性能，且此外，當黑矩陣係使用金屬氧化物、金屬氮化物、和金屬氧氮化物形
成時，能夠簡化製程並確保形成圖案的可靠性。
本說明書的一個例示具體實施例提出一種顯示裝置，其包括：基板，包括像素區和非像素區；黑矩陣，配置於基板的非像素區的至少一部分；和配置於基板的像素區中之像素電極及對應於像素電極的共同電極，其中像素區被配置於基板上同時彼此交錯的複數個閘極線和複數個數據線所分隔，非像素區包括含括薄膜電晶體、閘極線和數據線的佈線單元，且黑矩陣符合以下式1之0.004或更高且0.22或更低的值。
式1中，k是指黑矩陣的消光係數，t是指黑矩陣的厚度，和λ是指光的波長。
該黑矩陣可配置於顯示裝置的發射表面，且可用以防止光自包括配置於非像素區中之薄膜電晶體和閘極線和數據線之佈線單元的絲電極表面反射。
當外部光入射至黑矩陣，第一反射光，其自黑矩陣表面反射，存在，和第二反射光，其通過黑矩陣並自黑矩陣下部的佈線單元反射，存在。
圖1說明本說明書的一個像素區的例子。特別地，圖1出示被配備於具有異常摺線區之基板上的複數個閘極線101a和101b及複數個數據線201a和201b所分
隔的像素區。此外，電力連接至閘極線101b和數據線201a的薄膜電晶體301配置於像素區內以控制各像素區的電力訊號。
該黑矩陣可經由介於第一反射光和第二反射光之間的破壞性干擾而降低光反射。
本發明者發現當黑矩陣，其符合式1之0.004或更高且0.22或更低的值，配置於非像素區，可實現顯示器的高解析度，此藉由藉黑矩陣下方的佈線單元之破壞性干擾顯著降低光反射而達成。
特別地，第一反射光和第二反射光具有180°的相差並因此造成破壞性干擾之條件藉以下式2表示。
式2中，t為黑矩陣的厚度，λ為光的波長，n為黑矩陣的折射指數，和N為預定的奇數，如1、3、和5。
在破壞性干擾條件下的第一反射率可藉以下式3得到。
式3中，n為黑矩陣的折射指數，和k為黑矩陣的消光係數。
此外，在破壞性干擾條件下的第二反射率可藉以下式4得到。
式4中，Rmetal為在黑矩陣下的佈線單元的佈線電極表面的反射率，R1為黑矩陣的第一反射率，I0為入射光強度，n為黑矩陣的折射指數，k為黑矩陣的消光係數，和N為預定的奇數，如1、3、和5。
根據本說明書之例示具體實施例，第一反射率和第二反射率之間的差的絕對值可為0.13或更高且0.42或更低。
根據本說明書之例示具體實施例，λ可為550nm。即，光可具有550nm的波長。
根據本說明書之例示具體實施例，顯示裝置與黑矩陣下部接觸的同時，可另包括金屬層。
黑矩陣下部可以是指與被視為螢幕的面相反的面。
根據本說明書之例示具體實施例，金屬層可包括選自由Cu、Al、Mo、Ti、Ag、Ni、Mn、Au、Cr和Co所組成之群組中之一或二或更多種金屬。
根據本說明書之例示具體實施例，金屬層厚度可為10nm或更高或1μm或更低。
當外部光入射至黑矩陣中時，第一反射光，其自黑矩陣表面反射，存在，和第二反射光，其通過黑矩陣並自位於黑矩陣下部的金屬層反射，存在。經由介於第一反射光和第二反射光之間的破壞性干擾，金屬層可用以降低在黑矩陣表面上的光反射率。
根據本說明書之例示具體實施例，黑矩陣的厚度可為10nm或更高且100nm或更低。
根據本說明書之例示具體實施例，黑矩陣的厚度可為10nm或更高且100nm或更低。特別地，根據本說明書之例示具體實施例，黑矩陣的厚度可為20nm或更高且60nm或更低。
黑矩陣的厚度低於10nm時，會發生配置於非像素區中的佈線單元的光反射率未能經充分控制的問題。此外，當黑矩陣的厚度超過100nm時，會發生黑矩陣難以圖案化的問題。
根據本說明書之例示具體實施例，黑矩陣在550nm波長的光中的消光係數k可為0.1或更高且2或更低。特別地，根據本說明書之例示具體實施例，黑矩陣在550nm波長的光中的消光係數k可為0.4或更高且2或更低。
當消光係數在此範圍內時，能夠有效地控制配置於非像素區中的佈線單元的光反射率，藉此進一步改
良液晶顯示裝置的可見度。
消光係數可藉由使用此技術中習知的橢圓偏光儀(Ellipsometer)測定設備測定。
消光係數k亦可被稱為吸收係數，且係界定標的材料吸收預定波長的光之強度的指數。據此，入射光通過具有厚度t的黑矩陣且根據消光係數k程度第一次被吸收，且被黑矩陣下部中的電極層所反射的光再度通過具有厚度t的黑矩陣且第二次被吸收，及之後被外部反射。據此，黑矩陣的厚度和吸收係數的值為影響整體反射率的重要因素。據此，根據本說明書之例示具體實施例，其中在黑矩陣之吸收係數k和厚度t的預定範圍內可降低光反射率之範圍，以式1表示。
根據本說明書之例示具體實施例，黑矩陣在550nm波長的光中的折射指數n可為2或更高且3或更低。
在具有折射指數n和消光係數k之黑矩陣材料中發生第一反射，且在此情況中，決定第一反射的主要因素是折射指數n和吸收係數k。據此，折射指數n和吸收係數k彼此緊密相關，且光反射降低層的效果可在此範圍內被最大化。
根據本說明書之例示具體實施例，黑矩陣表面中的光反射率可為40%或更低。
根據本說明書之例示具體實施例，黑矩陣可包括選自由金屬氧化物、金屬氮化物、和金屬氧氮化物所
組成之群組中之一或多者。特別地，根據本說明書之例示具體實施例，黑矩陣可包括選自由金屬氧化物、金屬氮化物、和金屬氧氮化物所組成之群組中之一或多者作為主要材料。

根據本說明書之例示具體實施例，黑矩陣可包括鉬-氧氮化鈦。
根據本說明書之例示具體實施例，黑矩陣可以單層形成，且亦可以二或更多層形成。黑矩陣可具有無彩顏色，但其顏色未特別限於此。此處，無彩顏色系列中的顏色是指未選擇性地吸收入射至物體表面的光且當相關於各組件的光被均勻地反射和吸收時出現的顏色。
根據本說明書之例示具體實施例，像素電極和共同電極可包括選自由Cu、Al、Mo、Ti、Ag、Ni、Mn、Au、Cr和Co所組成之群組中之一或二或更多種金屬。
根據本說明書之例示具體實施例，非像素區可包括含括閘極線和數據線的佈線單元，且可包括介於佈線單元和黑矩陣之間的絕緣層。
根據本說明書之例示具體實施例，黑矩陣與基板的距離比與佈線單元的距離更近。
根據本說明書之例示具體實施例，黑矩陣與基板的距離比與佈線單元的距離更遠。
根據本說明書之例示具體實施例，黑矩陣可配置於基板的非像素區上，且佈線單元的至少一部分可配置於黑矩陣上。特別地，根據本說明書之例示具體實施例，佈線單元可配置於黑矩陣上，且可經由基板觀看螢幕。此構造的一個例子示於圖3至6。此情況中，優點在於不須在顯示裝置的擋板區中額外形成覆蓋部分。即，黑
矩陣可作為擋板區之存在的覆蓋部分，並因此能夠根據擋板區的覆蓋部分而減少一個步驟。
根據本說明書之例示具體實施例，薄膜電晶體連接至含括於各個像素區的一面處的各個閘極線和數據線。
根據本說明書之例示具體實施例，薄膜電晶體包括自閘極線分支的閘極和配置於閘極上的半導體層及介於其間的絕緣層。此外，半導體層以介於其間的電阻接觸層連接至源極和汲極，且源極與數據線連接。
閘極線供應來自閘極驅動器的掃描訊號，且數據線供應來自數據驅動器的影像訊號。
根據本說明書之例示具體實施例，顯示裝置可為液晶顯示裝置，其在各像素區中包括濾色層，並包括配置於與濾色層相同平面上的像素電極和共同電極。
圖2說明根據本說明書的一個例示具體實施例之液晶顯示裝置的截面。特別地，由閘極310、半導體層320、源極330、和汲極340所形成的薄膜電晶體301配置於基板上，連接至閘極的像素區被連接至閘極的閘極線(未示)和數據線201所分隔，濾色層510和520配置於像素區中，在各像素區內，共同電極601和像素電極701並排配置於濾色層510和520上。此外，基板可分割成非像素區2000和像素區3000，黑矩陣801配置於非像素區中，之後配置液晶定向層901。圖2未說明配置於液晶定向層901上的液晶層。但是，除了圖2所示的構造以
外，根據本發明之例示具體實施例之液晶顯示裝置可以各種構造施用。
此外，不同於具有圖2之構造的液晶顯示裝置，在液晶顯示裝置具有相反構造(即，像素單元的螢幕經由基板觀看之構造)的情況中，黑矩陣與基板的距離比與佈線單元的距離更近。此情況中，形成黑矩陣之後，必須於高溫條件進行形成薄膜電晶體等的程序，因此難以使用以有機材料作為黑矩陣。在這方面，根據本說明書之黑矩陣未使用有機材料，所以可能確保於高溫的安定性。
圖3說明根據本說明書的一個例示具體實施例之液晶顯示裝置的截面。特別地，圖3提出具有根據本說明書的一個例示具體實施例之相反構造且黑矩陣的位置不同於圖2之情況的液晶顯示裝置的例子。即，根據圖3，黑矩陣801形成於基板上，絕緣層1040形成於其上，接著，由閘極310、半導體層320、源極330、和汲極340所形成的薄膜電晶體301配置於絕緣層1040上，像素區被連接至閘極的閘極線(未示)和數據線201所分隔，濾色層510和520配置於像素區中，共同電極601和像素電極701並排地配置於濾色層510和520上，並配備液晶定向層901。此外，基板可被分割成非像素區2000和像素區3000。但是，除了圖3中所示的構造以外，根據本發明之例示具體實施例之液晶顯示裝置可以各種構造施用。
此外，在圖3之情況的構造中，可排除在形成黑矩陣之後配備絕緣層1040，且亦可形成佈線單元。
一個構造實例例示於圖4中。特別地，圖4出示閘極301直接形成於圖3的構造中之黑矩陣801上的情況。
在具有圖3和4之相反構造之液晶顯示裝置中，優點在於不須配備用於圖2的構造中所須之隱藏電極墊部分的覆蓋部分。特別地，在具有圖3所示構造的液晶顯示裝置中，能夠阻斷佈線單元經由黑矩陣的光反射，所以可以不添加用於阻斷光反射的覆蓋部分。
在根據本說明書之例示具體實施例之液晶顯示裝置中，像素電極和共同電極各者包括複數個導電線，而像素區內的像素電極和共同電極可以並排配置。特別地，像素電極和共同電極可以交替地配備於各像素區內。據此，可藉由在各像素區內形成水平電場而驅動液晶分子。
在根據本說明書之例示具體實施例之液晶顯示裝置中，共同電極接收共同電壓(其為驅動液晶的參考電壓)，並因此而在像素電極(像素電壓訊號供應至彼)和共同電極(共同電壓施用至彼)之間形成水平電場，使得以水平方向排列的液晶分子因介電異向異性而旋轉。此外，光通過像素區的透光率根據液晶分子的旋轉程度而變化，因此可實現影像。
在根據本說明書之例示具體實施例之液晶顯示裝置中，像素電極和共同電極之至少一者可配備於濾色層的重疊部分上。
濾色層的重疊部分是指具有不同顏色的濾色
器彼此接觸的區域，且可為圖2中之不同的濾色層510和520彼此接觸的區域。
當像素電極或共同電極配備於濾色層的重疊部分上時，優點在於在顯示器被驅動時，可防止濾色層的重疊部分中之顏色混合。
配備於各像素區中的濾色層可為紅、綠、或藍濾色層。此外，取決於情況，可在任一像素區內配備白濾色層。紅濾色層、綠濾色層、藍濾色層、和白濾色層各者可形成一個像素單元，且此一個像素單元可經由通過紅濾色層、綠濾色層、藍濾色層、和白濾色層並發射的色光而顯示影像。
根據本發明之例示具體實施例顯示裝置可為有機發光顯示裝置，其包括在各像素區上的有機材料層，該有機材料層配備於像素電極和共同電極之間。
圖5說明根據本說明書的一個例示具體實施例有機發光顯示裝置的截面。特別地，由閘極310、半導體層320、源極330、和汲極340所形成的薄膜電晶體301配置於基板401上，像素區被連接至閘極310的閘極線(未示)和數據線201所分隔，有機發光裝置，其各者包括像素電極701、有機材料層550和560、及共同電極601，配備於像素區內，各個有機發光裝置彼此藉隔膜901分隔。此外，閘極310和半導體層320可藉絕緣層1010隔離。絕緣層1010可為閘極絕緣層。此外，基板可被分隔成非像素區2000和像素區3000，黑矩陣801配備
於非像素區中，形成絕緣層1030，之後形成薄膜電晶體。但是，除了圖5所示的構造以外，根據本發明之例示具體實施例之有機發光顯示裝置可以各種構造施用。
此外，在圖5之情況的構造中，可以排除在形成黑矩陣之後配備絕緣層1030，亦可形成佈線單元。構造的一個例子示於圖6。特別地，圖6出示閘極301直接形成於圖5之構造中的黑矩陣801上之情況。
在根據本揭示之例示具體實施例之有機發光顯示裝置中，像素電極可為透明電極。
在根據本揭示之例示具體實施例之有機發光顯示裝置中，有機材料層可包括一或多個發射層，且可另包括選自由電洞注入槽、電洞傳輸層、電洞阻斷層、電荷產生層、電子阻斷層、電子傳輸層、和電子注入層所組成之群組中之一或二或更多者。
電荷傳輸層是指當施以電壓時，產生電洞和電子的層。
在根據本揭示之例示具體實施例之有機發光顯示裝置中，像素電極可為陽極，共同電極可為陰極。此外，像素電極可為陰極，而共同電極可為陽極。
具有高功函數以有助於電洞注入有機材料層中之材料通常可為陽極材料。可用於本發明之陽極材料的特別的例子包括金屬(如釩、鉻、銅、鋅、和金或其合金)、金屬氧化物(如氧化鋅、氧化銦、氧化銦錫(ITO)、和氧化銦鋅(IZO))、金屬和氧化物之組合

陰極材料不僅限於陰極，且可作為陽極材料。
