Description

この発明は、保護板一体型表示パネルに関する。The present invention relates to a protective plate integrated display panel .

液晶表示パネルとして、液晶表示素子の観察側に、前記液晶表示素子の観察側の面を保護し、且つ前記液晶表示素子を補強するための観察面保護板を、前記液晶表示素子との間に間隙を設けて配置し、前記液晶表示素子と観察面保護板とを、これらの間の間隙に設けられた樹脂層により接合して一体化させた保護板一体型液晶表示パネルがある。   As the liquid crystal display panel, an observation surface protection plate for protecting the observation side surface of the liquid crystal display element and reinforcing the liquid crystal display element is provided between the liquid crystal display element and the observation side of the liquid crystal display element. There is a protective plate-integrated liquid crystal display panel in which the liquid crystal display element and the observation surface protection plate are joined and integrated by a resin layer provided in the gap between them.

一方、前記液晶表示素子には、液晶層を挟んで対向する観察側とその反対側の一対の基板のうちの一方の基板に、他方の基板の外方に張出す張出部が形成され、この張出部の前記他方の基板と対向する側の面上にドライバ素子が搭載されたものがある。   On the other hand, in the liquid crystal display element, an overhanging portion that protrudes outward from the other substrate is formed on one of the pair of substrates on the opposite side to the observation side facing the liquid crystal layer, In some cases, a driver element is mounted on the surface of the overhanging portion facing the other substrate.

このドライバ搭載型の液晶表示素子を備えた保護板一体型液晶表示パネルとしては、従来、観察側の基板に張出部を形成した液晶表示素子の観察側に観察面保護板を配置し、前記液晶表示素子の観察側の面の全体を、前記張出部を含んで、樹脂層により前記観察面保護板と接合したものがある（特許文献１参照）。
特開２００７−１１４７３７号公報 As the protection plate integrated liquid crystal display panel provided with this driver-mounted liquid crystal display element, conventionally, an observation surface protection plate is disposed on the observation side of the liquid crystal display element in which an overhang is formed on the observation side substrate, There is one in which the entire surface on the observation side of the liquid crystal display element is joined to the observation surface protection plate with a resin layer including the protruding portion (see Patent Document 1).
JP 2007-114737 A

上記従来の保護板一体型液晶表示パネルは、前記液晶表示素子の観察側基板に形成された強度的に弱い張出部を観察面保護板により補強することができるが、前記張出部の観察側とは反対側の基板と対向する側の面上に搭載されたドライバ素子を保護することができない。   In the conventional protective plate-integrated liquid crystal display panel, the overly weak portion formed on the observation side substrate of the liquid crystal display element can be reinforced by the observation surface protective plate. The driver element mounted on the surface on the side opposite to the substrate opposite to the side cannot be protected.

また、ＴＦＴ（薄膜トランジスタ）をアクティブ素子としたアクティブマトリックス液晶表示素子においては、ドライバ素子を搭載するための張出部が形成された基板に、複数の画素電極と、これらの画素電極にそれぞれ接続された複数のＴＦＴと、各行のＴＦＴにゲート信号を供給する複数の走査線及び複数の信号線と、各行の複数の画素電極との間にそれぞれ補償容量を形成する複数の容量電極とが設けられる。   Further, in an active matrix liquid crystal display element using TFTs (thin film transistors) as active elements, a plurality of pixel electrodes and a plurality of pixel electrodes are connected to a substrate on which a protruding portion for mounting a driver element is formed. In addition, a plurality of TFTs, a plurality of scanning lines and a plurality of signal lines for supplying gate signals to the TFTs in each row, and a plurality of capacitance electrodes for forming compensation capacitors between the plurality of pixel electrodes in each row are provided. .

しかし、上記従来の保護板一体型液晶表示パネルは、前記液晶表示素子を、前記張出部が形成された一方の基板、つまり画素電極とＴＦＴと走査線及び信号線と容量電極が設けられた基板を観察側に向けて配置するため、観察側から入射し、前記走査線及び信号線や前記容量電極によって反射された光が観察側に出射し、見かけ上のコントラストが低下する。   However, in the above conventional protective plate integrated liquid crystal display panel, the liquid crystal display element is provided with one substrate on which the protruding portion is formed, that is, a pixel electrode, a TFT, a scanning line, a signal line, and a capacitor electrode. Since the substrate is arranged toward the observation side, light incident from the observation side and reflected by the scanning lines, the signal lines, and the capacitor electrodes is emitted to the observation side, and the apparent contrast is lowered.
