Abstract

The invention discloses an electrowetting display device. The electrowetting display device comprises a plurality of pixel areas, and each pixel area includes a pixel perimeter area and an active area. The electrowetting display device also comprises a first substrate, a plurality of first electrodes, a hydrophobic layer, a plurality of barrier walls, a second substrate, a plurality of second electrodes, a polar liquid and a non polar liquid. The first electrode is positioned on the first substrate. Each second electrode includes a first sub electrode part and a second sub electrode part which are arranged in the corresponding active area and mutually and electrically connected, a first distance is present between the first sub electrode part and the hydrophobic layer, a second distance is present between the second sub electrode part and the hydrophobic layer, and the first distance is larger than the second distance. The polar liquid and the non polar liquid are arranged between the second electrode and the hydrophobic layer.

Description

technical field [0001] The invention relates to an electrowetting display device, especially an electrowetting display device with multiple gaps. Background technique [0002] An electrowetting display device is a display device that uses electrowetting force to control the movement of non-polar liquid and polar liquid to achieve display effect. The electrowetting display device mainly includes two substrates, two electrodes respectively placed inside the two substrates, and a non-polar liquid and a polar liquid which are arranged between the two electrodes and are immiscible with each other. The voltage difference applied between the two electrodes can change the hydrophilic effect of the electrodes, thereby changing the contact angle. That is to say, in the absence of voltage difference, the electrode surface is more hydrophobic and oleophilic, and after the voltage difference is applied, the electrode surface will become more hydrophilic and oleophobic, so the area cover...
