The contact panel with contact panel of the external hanging type of panel is controlled (for example, Japanese Unexamined Patent Publication 2012-230491 publication (patent documents
1)).The liquid crystal display device with contact panel of the external hanging type due to overlapping with contact panel on liquid crystal display device, because
This, not only thickness can be thickening, also exist see the sensor patterns of contact panel so so-called perspective the problem of.
Therefore, such perspective in order to prevent, propose to have liquid crystal display device face side polarizer and liquid crystal layer it
Between be configured with the embedded liquid crystal display device with contact panel of contact panel (for example, Japanese Unexamined Patent Publication 8-161116
Publication (patent document 2)).In such embedded liquid crystal display device with contact panel, because than positive lateral deviation
Tabula rasa inside (liquid crystal layer side) configures contact panel, therefore, light isotropism is required for contact panel substrate.Therefore,
For the PET substrate of the liquid crystal display device with contact panel of external hanging type its birefringence, big (light is each
It is low to the same sex), therefore, it is impossible to suitable for the embedded liquid crystal display device with contact panel.Therefore, in embedded band
In the liquid crystal display device of contact panel, as contact panel substrate, it is necessary to which use is double by cycloolefin polymer substrate etc.
Reflect the substrate that the resin of small (having light isotropism) is formed.
However, because the heat resistance of cycloolefin polymer is low, formed on the surface of cycloolefin polymer substrate
It during transparency electrode, can not at high temperature be heated, have the problem of electric conductivity of transparency electrode is lower.Therefore, cyclenes
Hydrocarbon polymer substrate is not suitable as the contact panel base of the embedded liquid crystal display device with contact panel of giant-screen
Plate.
