An object of the present invention is to provide an EL display device, which has a high operating performance and reliability. Trace information collection and trace information export are prohibited in the first state. The luminous flux of the primarily diffused lights is condensed with respect to a first orientation component on a plane in parallel with the LCD panel, and then partially and secondarily diffused for extending a view angle of pixels of the LCD panel. The powertrain includes an engine and torque converter that is continuously connected to one of the planetary gear members and an output member that is continuously connected with another one of the planetary gear members. The methods and kits also allow prediction of disease outcome and staging of patients with regard to therapy.
