Display device and Akute blanking matrix substrate

摘要

PPROBLEM TO BE SOLVED: To provide a display device which prevents parasite capasitance from being generated on data lines or driving circuits by using a bank layer for prescribing a formation area of an organic semiconductor film on a substrate. PSOLUTION: When the organic semiconductor film for constituting a light emitting element like an electroluminescence element or LED element is formed in a pixel area 7, a bank layer 'bank' is formed of black resist around it. This bank layer 'bank' is formed even between a data line 'sig' for supplying an image signal to a 1st TFT 20 and a retained capacitance 'cap' in the pixel area and a counter electrode 'op' to prevent the parasite capasitance from being generated on the data line 'sig'.
