The present invention has as an object to, by controlling how oil injected into a liquid drop control device wet spreads, make it harder for bubbles to remain in a cell. A liquid drop control device of the present invention is characterized in that in at least one substrate, there is a gap between an end face of a lyophobic layer and a seal material and the lyophobic layer and the seal material make contact with each other in at least one place.

Method for manufacturing liquid drop control device, liquid drop control device, and display device

An electrowetting device according to the present disclosure includes: an electrode substrate having a first substrate, a plurality of first electrodes formed on the first substrate, a dielectric layer formed on the plurality of first electrodes, and a first hydrophobic layer formed on the dielectric layer; a counter substrate disposed opposite the electrode substrate with a predetermined gap interposed therebetween, and having a second substrate, a second electrode formed on the second substrate, and a second hydrophobic layer formed on the second electrode; and a sealing member located in an outer peripheral region of the electrode substrate, and the sealing member attaching the electrode substrate and the counter substrate together. The gap between the first and second hydrophobic layers is defined by the sealing member, and a portion of the sealing member forms an injection hole to allow a droplet to be injected into the gap. An opening region of the outer peripheral region that includes the injection hole does not overlap the counter substrate as viewed from the normal direction of the counter substrate.

Electrowetting device and method for manufacturing electrowetting device

The disclosure provides an electrowetting device in which a sealing material is formed with satisfactory precision while maintaining a good adhesive property between both substrates. In a first hydrophobic layer () and a second hydrophobic layer (), opening patterns (, and) are provided, and an active substrate () and a common electrode substrate () are bonded together with a sealing material () provided in the opening patterns (, and) such that a space is formed between the active substrate () and the common electrode substrate ().
