Emissive element and display device using such element

An EL element (60) comprises an anode (61), a cathode (67), and an emissive element layer (66) interposed between the two electrodes. A TFT is connected to the anode (61) at its source electrode (33s). The peripheral portion of the anode (61) and the entire region over the TFT are covered with a planarizing insulating film (17), and a part of the exposed portion of the anode (61) is connected to the emissive element layer (66). According to the above arrangement, it is possible to prevent disconnection of the emissive element layer (66) which may be caused by an uneven surface created by the thickness of the anode (61), and to avoid formation of a short circuit between the anode (61) and the cathode (67).

Programmable logic device

An object is to provide a programmable logic device having logic blocks connected to each other by a programmable switch, where the programmable switch is characterized by an oxide semiconductor transistor incorporated therein. The extremely low off-state current of the oxide semiconductor transistor provides a function as a non-volatile memory due to its high ability to hold a potential of a gate electrode of a transistor which is connected to the oxide semiconductor transistor. The ability of the oxide semiconductor transistor to function as a non-volatile memory allows the configuration data for controlling the connection of the logic blocks to be maintained even in the absence of a power supply potential. Hence, the rewriting process of the configuration data at starting of the device can be omitted, which contributes to the reduction in power consumption of the device.

Thin organic alignment layers with a batch process for liquid crystal displays

A method to form alignment layers on a substrate of an LCD is disclosed. The substrate is placed in a vacuum chamber and undergoes a purging process. The purging process heats the substrates and removes water vapor from the vacuum chamber. Specifically, the vacuum chamber is evacuated to a low pressure and refilled with a preheated inert gas. Evacuation of the vacuum chamber and refilling of the vacuum chamber is repeated several times. The alignment layer is then deposited using vapor deposition. Alternatively, plasma enhanced vapor deposition can be used for depositing the alignment layer. Furthermore, plasma cleaning prior to the deposition of the alignment layer can used clean the substrate.
