Definitions
- the present invention relates to a transparent substrate for an optical element, a polarizing plate for a liquid crystal display device using the same, and an organic electroluminescence element.
- Optical elements used in thin devices such as organic electroluminescence (organic EL) lighting devices and liquid crystal display devices are required to have high light transmittance, transparency, and rigidity.
- a glass substrate is used as the substrate.
- the glass substrate is fragile, is not easy to handle, and is not easy to manufacture.
- a transparent and flexible resin film can be wound into a roll and handled. Is easy, can be manufactured efficiently, can improve design properties, and is inexpensive, and is useful as a substitute for a glass substrate.
- the resin film allows gas such as water vapor to pass therethrough
- an optical element using a resin substrate instead of a glass substrate water vapor that has passed through the resin substrate penetrates into the optical element, and the optical element is It will be altered.
- the organic EL lighting device using an organic EL element in which a light emitting film containing an organic EL is formed on a resin substrate the organic EL changes to a substance that does not participate in light emission by reacting with an electrode component due to the presence of water.
- a portion that does not emit light a so-called dark spot, appears as a spot on the surface light source, and the quality as illumination decreases.
- water that has passed through the resin substrate or water that has entered from the side surface constitutes a polarizer contained in the polarizing film, for example, the decomposition of a complex of polyvinyl alcohol (PVA) and iodine, absorption of water
- PVA polyvinyl alcohol
- the optical anisotropy of the polarizing film changes due to the dimensional change caused by the emission, or the function of the optical compensator that is provided between the substrate and the polarizing film and expands the viewing angle is hindered.
- an I 5 -PVA complex having a peak near 600 nm and a broad absorption band, reddening and easily decomposing under high temperature and high humidity, and a peak around 480 nm.
- examples thereof include an I 3 -PVA complex that has a broad absorption band and decomposes to become blue.
- a substrate with improved gas barrier properties has been developed compared to a resin substrate used for such an optical element.
- an organic EL element a film such as polyester, an organic EL element provided with a silicon oxynitride layer (Patent Document 1), a film such as polyethylene terephthalate, a polysilazane having a specific thermal expansion coefficient, etc.
- Patent Document 2 An organic EL device using a gas barrier film having a stress relaxation layer and a gas barrier layer such as silica (Patent Document 2), an inorganic layer such as silicon nitride, a layer having a small contact angle, and a contact angle larger than this
- Patent Document 3 an element body such as an organic EL element in which a resin substrate having an organic film layer composed of layers is used to move intruded water to the side opposite to the element side.
- Patent Document 4 a polarizing plate of a liquid crystal display device in which a silicon oxide film having a specific contact angle is formed on a transparent substrate film, and a polarizing element is laminated thereon to improve gas barrier properties.
- the inorganic layer containing silicon or the like formed on the resin film of the substrate is likely to be cracked and may be peeled off, resulting in a decrease in gas barrier properties. There's a problem.
- a transparent substrate for optical elements that can sufficiently suppress the permeation of water vapor through the resin substrate.
- the subject of this invention is providing the transparent base material for optical elements which can suppress generation
- An object of the present invention is to provide a transparent substrate for an optical element that can be extended.
- the present invention relates to a transparent substrate for an optical element having an inorganic layer and a hydrophilic layer sequentially laminated on a transparent resin film, a polarizing plate for a liquid crystal display device using the same, and an organic electroluminescence element
- the present invention relates to a liquid crystal display device and an organic electroluminescence lighting device.
- the transparent base material for optical elements of the present invention can suppress the generation of cracks, and these can be applied to optical elements such as organic EL elements used in organic EL lighting devices and polarizing plates used in liquid crystal display devices.
- optical elements such as organic EL elements used in organic EL lighting devices and polarizing plates used in liquid crystal display devices.
- the lifetime of the organic EL lighting device and the liquid crystal display device can be extended.

Description
2、2a、2b、2c 無機層

4 疎水層(樹脂層)
B 光学素子用透明基材
20 有機層
30 偏光膜
31 保護フィルム(樹脂製フィルム)
[実施例1]
光学素子用透明基材を以下のように調製した。可撓性フィルム1に、厚さ100μmのポリエチレンナフタレート(テオネックスQ65FA;帝人デュポンフィルム社製)を用い、その上に、窒化ケイ素膜層2、親水層3と、疎水層4を順次積層した。窒化ケイ素膜は、プラズマCVD装置を用いて、基板温度100℃、圧力120Paに保ち、SiH4、NH3、H2、N2ガスをフローレート10、20、200、200sccmで導入し、電源周波数13.56MHz、投入電力500Wで、厚さ100nmの透明無機膜を形成した。次に、親水層を形成した。モノマーとしてメタクリル酸メチル、溶剤としてプロピレングリコールモノメチルエーテルアセテート、架橋剤としてメタアクリル酸エステルモノマー、分散レベリング剤として変性ポリアクリレート、開始剤としてベンゾフェノン系開始剤を用いてスピンコート法にて塗布を行った。2000rpmで20秒間回転させた後、0.6kPaで90秒間減圧乾燥を行い、さらに90℃で5分間加熱乾燥を行った。高圧水銀灯によりUVを、積算光量2000mJ/cm2となるよう照射し、さらに110℃で40分間焼成を行い、塗布膜厚500nmを得た。その後、疎水層を形成した。モノマーとして5-メチル-2-ノルボルネン、溶剤としてエチルベンゼン、架橋剤としてケトンパーオキシド、分散レベリング剤として変性ポリアクリレート、光反応性モノマーとして2-ヒドロキシエチルメタクリレート、開始剤としてベンゾフェノン系開始剤を用いてスピンコート法にて塗布を行った。2000rpmで20秒間回転させた後、1.3kPaで120秒間減圧乾燥を行い、さらに60℃で5分間加熱乾燥を行った。高圧水銀灯によりUVを、積算光量2000mJ/cm2となるよう照射し、さらに110℃で30分間焼成を行い、塗布膜厚500nmを得た。
無機層、親水層、疎水層を作製せず樹脂製フィルムをそのまま用いた他は、実施例1と同様に、有機EL照明パネルを作製し、高温高湿試験を行った。ダークスポットの発生について、結果を図4に示す。発光部のシュリンク、光学素子用透明基材のクラックが発生・成長し、ダークスポットに起因するショートにより200時間後には非点灯となった。
偏光膜30の両面に、それぞれ厚さ10μmのアクリル系粘着層を介して、樹脂製フィルムを厚さ70μmのトリアセチルセルロースフィルムに変えた他は、実施例1と同様に作製した光学素子用透明基材と、厚さ70μmのトリアセチルセルロースフィルムの保護フィルム31とを接着して、図3に示す偏光板を作製した。厚さ70μmのトリアセチルセルロースフィルムは、以下の方法により得た。トリアセチルセルロースの塩化メチレン溶液を、ステンレス等の平板基板上に均一に塗布し、47kPaで120秒間減圧乾燥を行い、さらに、50℃にて5分間加熱乾燥を行った。次にステンレス板より剥離し、フィルムに応力がかからない状態で、150℃で10分間乾燥させて、厚さ70μmの保護フィルムを得た。
無機層、親水層、疎水層を作製せず透明可撓性基材をそのまま用いた他は、実施例2と同様に偏光板を作製し、高温高湿試験を行い、液晶パネルの光漏れ、色ズレ・色付き、光学素子用透明基材のクラックの有無を観察した。色度変化を図5(b)に示し、1000時間経過後の液晶パネルの黒表示時の斜め視野からの画像状態を図6(b)に示す。光学素子用透明基材のクラックは1200時間後に認められた。
図7に示すように、無機層として、樹脂製フィルム1上に、順次、窒化酸化ケイ素膜(第一層)2a、窒化ケイ素膜(第二層)2b、酸化ケイ素膜(第三層)2cを以下の方法により作製した。窒化酸化ケイ素膜は、プラズマCVD装置を用いて、基板温度100℃、圧力120Paに保ち、SiH4、O2、N2ガスを流量10、20、200sccmで導入し、電源周波数13.56MHz、投入電力500Wで、厚さ70nmの透明無機膜を形成した。次に、窒化ケイ素膜を、上記と同じ条件で、SiH4、NH3、H2、N2ガスを流量10、20、200、200sccmで成膜し、厚さ100nmの透明無機膜を形成した。さらに、酸化ケイ素膜を、上記と同じ条件で、SiH4、O2、H2ガスを流量10、50、200sccmで成膜し、厚さ100nmの透明無機膜を形成した。
実施例3に用いた光学素子用透明基材上に、実施例2と同様にして、図8に示す偏光板を作製し、液晶パネルを作製し、高温高湿試験を行い、光学素子用透明基材のクラック、液晶パネルの光漏れ、色ズレ・色付きについて観察した。
実施例2で得られた図3に示す偏光板のトリアセチルセルロースフィルム31上に、厚さ10μmのアクリル系接着層を介して、光学補償フィルム32を接着することにより積層膜とした。光学補償フィルム上に、実施例1と同様に、無機層、親水層、疎水層を作製し、光学素子用透明基材を作製した。得られた光学素子用透明基材のトリアセチルセルロースフィルムの裏面に、実施例1と同様にして、光学素子用透明基材を作製し、図9に示す偏光板を作製し、実施例2と同様にして、液晶パネルを作製し、高温高湿試験を行い、光学素子用透明基材のクラック、液晶パネルの光漏れ、色ズレ・色付きについて観察した。
