摘要:
A liquid crystal device, suitably included in e.g., an organic EL device, is formed of a pair of electrodes and a plurality of layers disposed between the electrodes and including at least one liquid crystal layer. The liquid crystal layer comprises a liquid crystal composition having an electronic carrier-transporting function and comprising at least two compounds including at least one electron-donating compound or electron-accepting compound having a &pgr;-electron conjugated structure. As a result of doping the liquid crystal layer with the electron-donating or electron-accepting compound, the current conduction performance of the liquid crystal layer is improved presumably due to the generation of free carriers therein, whereby a functional device including the liquid crystal device can be improved as a whole.

In accordance with a series of consecutive operations by a user to the touch panel involving touch operation, drag operation, and release operation, the following are accepted: the selection of an action area from among one or more action areas displayed on the basis of a touched area on the touch panel at the time of a user's touch operation, and the execution of an action corresponding to the action area.
摘要:
In manufacturing an LSI, or semiconductor integrated circuit device, the step of assembling device (such as resin sealing step) is normally followed by a voltage-application test in an environment of high temperature (e.g., from 85 to 130° C.) and high humidity (e.g., about 80% RH). It has been found that separation of a titanium nitride anti-reflection film from an upper film and generation of cracks in the titanium nitride film at an upper surface edge part of the aluminum-based bonding pad applied with a positive voltage in the test is caused by an electrochemical reaction due to moisture incoming through the sealing resin and the like to generate oxidation and bulging of the titanium nitride film. These problems are addressed by removing the titanium nitride film over the pad in a ring or slit shape at peripheral area of the aluminum-based bonding pad.
