摘要： PROBLEM TO BE SOLVED: To secure stable emission luminance among pixels. SOLUTION: An intra-pixel control switch 15 for stopping the drive of a light emitting element 13 is included in each pixel 1. Changes in emission luminance due due to the characteristic variation of the light emitting element 13 are suppressed by feeding back a measured result of a current measuring means formed on one end of a power supply line 4 to a drive signal of the light emitting element 13.

摘要： PROBLEM TO BE SOLVED: To provide an organic EL display device improved in color purity adjustment and particularly in white purity without increasing formation processes.
SOLUTION: Banks BNK are formed on lower electrodes BEL being pixel electrodes on a unit pixel basis formed on an insulation film INS formed on a principal surface of a glass substrate. The bank BNK has a shape of a dike surrounding the pixel for every pixel, and an organic EL emission layer is formed in a region surrounded by the bank BNK. A green luminescent layer (G luminescent layer), a blue luminescent layer (B luminescent layer), and a red luminescent layer (R luminescent layer) are formed between the bank BNK and the bank BNK. A white luminescent layer (G+B+R) is formed in a region of a white pixel concurrently with the formation of the chromatic luminescent layers by stacking and forming luminescent layers of three colors such as a green luminescent (G luminescent layer), a blue luminescent layer (B luminescent layer), and a red luminescent layer (R luminescent layer). An upper electrode UEL is formed by commonly covering the green luminescent (G luminescent layer), the blue luminescent layer (B luminescent layer), the red luminescent layer (R luminescent layer), and the white luminescent layer (G+B+R).

摘要： PROBLEM TO BE SOLVED: To display an image having improved uniformity of light emission and high image quality in an image display apparatus using an FED and an organic EL device.
