摘要： A pixel structure is provided in which a functional thin film having a uniform thickness can be formed in a pixel region, and an electro-optic device is obtained having superior uniformity of light brightness by the use of the above pixel structure. The functional thin film is formed on a thin film-forming surface surrounded by a partition for defining the pixel region. In this step, since the partition described above is formed of a first partition having a lyophilic surface and a second partition which is provided thereon and which has a lyophobic surface, and the first partition has parts which are not covered with the second partition, a liquid material for forming the functional thin film, which is filled inside the partition, can be formed into a film having a uniform thickness after drying due to the interaction between the lyophilic and the lyophobic properties.

摘要： To reduce the time for writing a voltage onto a gate of a driving transistor. In an initialization period, a node B is fixed to an initial voltage VINI, transistors are turned on, and a current flows into an OLED element, such that a voltage according to the current is held at the node A. Thereafter, the transistors are sequentially turned off, such that a threshold voltage of a driving transistor is held at the node A. In a writing period, a transistor is turned on and a data signal X-j is supplied, such that a voltage of the node B varies by the amount according to the current flowing into the OLED element. The voltage of the node A varies from the threshold voltage by the amount which is obtained by dividing the voltage variation by a capacitance ratio. In a light-emitting period, the transistor is turned on, such that a current according to the voltage of the node A flows into the OLED element.
