A display device includes a plurality of data drivers which are cascade-connected, and prevents variation of the duty ratio of a signal caused by accumulation of errors. Furthermore, the invention provides antibodies directed against the allergen and to the use of the polypeptides, polynucleotides andor antibodies in therapy and diagnosis of allergic disorders. Using the interaction of colored signals from the positive control area and the analyte binding area, a recognizable symbol is revealed on the device that correlates with the test results, and appears as the test is conducted. The retrieved documents are divided into subsets of similar documents, where each subset of the subsets of similar documents is described in terms of a subset pattern.
