Abstract

An electronic ink display device with a frontplane laminate and a TFT array substrate is provided. In the TFT array substrate, a first metal layer and a dielectric layer are disposed on a first substrate. The dielectric layer covers the first metal layer. A second metal layer is disposed on the dielectric layer. The first metal layer includes scan lines and gates, and the second metal layer includes data lines and sources/drains. The first substrate is divided into multiple pixel areas by the data lines and the scan lines. The gates and the sources/drains are disposed inside the pixel areas. A channel layer is disposed on the dielectric layer between the gates and the sources/drains. Pixel electrodes are disposed inside the pixel areas and connected to the drains. An electronic ink material layer of the frontplane laminate is disposed between a transparent electrode layer and the TFT array substrate.
