Transparent electrode laminate and touch screen panel including the same

摘要

Disclosed is a transparent electrode laminate including: sensing electrodes including first patterns formed in a first direction, and second patterns formed in a second direction; bridge electrodes configured to electrically connected separated unit patterns of the second patterns; and an insulation layer disposed between the sensing electrodes and the bridge electrodes, wherein metal patterns are formed on the insulation layer exposed between the first pattern and the second pattern, thereby obtaining a high transparency by minimizing a difference in reflectance for each position and reducing the pattern visual recognition.

1. A transparent electrode laminate, comprising:
a sensing electrode including first patterns formed in a first direction and second patterns formed in a second direction; a bridge electrode to electrically connect separated unit patterns of the second patterns; an insulation layer disposed between the sensing electrode and the bridge electrode; and a metal pattern formed on the insulation layer exposed between the first pattern and the second pattern; wherein the metal pattern satisfies the following Equation 1:
0.99≦[[(Area ratio of the metal pattern on the insulation layer)×(Total reflectance of the metal pattern)+(1−(Area ratio of the metal pattern on the insulation layer))×(Total reflectance of portion without the metal pattern on the insulation layer)]/(Total reflectance of the sensing electrode and the bridge electrode)]≦1.01  [Equation 1] wherein, the total reflectance is a value of adding an interface (surface) reflectance to the respective reflectances.
