Filed: 2001-08-10
Abstract: PURPOSE: To suppress the decrease of a yield due to short-circuit between electrodes and the like, while satisfactory aperture ratio and auxiliary capacity are secured. CONSTITUTION: Only a source electrode 23 is formed as an electrode layer directly under a contact hole H1 and electrode layers are never overlapped by one another. By this reason, even if the part up to the gate insulating film 26 is immersed in etchant when etched, the short-circuit between the electrodes never occurs. An electrode 24 for forming the auxiliary capacity and a transparent pixel electrode 2b occupy nearly the same region and relatively large capacity is secured by the both electrodes having relatively large area. And satisfactory aperture ratio can be secured, since e.g. an auxiliary capacity common electrode to be a light shielding region does not exist in the region where the transparent pixel electrode 2b is formed.

Abstract: PURPOSE: A method for accessing management information in an EMS(Element Management System) is provided to form a tree as managed objects having only member variables, retrieve an MIB(Management Information Base) using a hash table in case that management is requested from an EMS server for searching a necessary managed object, and directly access a relation using an address retrieved from the corresponding managed object. CONSTITUTION: If management information is acquired according to the request of an operator or a management request message is received from an EMS server which wants to change an attribute value of a managed object(S14), an EMS agent analyzes the management request message received from the EMS server and judges whether the management request message is a set command for changing the attribute value of the managed object(S16). If the management request message is the set command, the EMS agent transmits the set command to a corresponding application processor(S18). The application processor receives the set command from the EMS agent, and changes the attribute value of the corresponding managed object according to the set command(S20). The application processor notifies the EMS server that the attribute value of the managed object is changed through the EMS agent, and searches a corresponding managed object from an MIB using a hash table(S22). The application processor directly accesses a corresponding relation in which real management information is stored using a specific address of a relation indicated by a member variable of the searched managed object through a management relation table, and stores the changed attribute value in the corresponding relation(S22).
