Abstract: An organic EL display device 1 includes: an organic EL element 4 provided above an element substrate 10; and a sealing film 2 formed above the element substrate 10 so as to cover the organic EL element 4, and made of silicon nitride (SiNx). The sealing film 2 is comprised of a first sealing layer 25, a second sealing layer 26 provided on the surface of the first sealing layer 25, and a third sealing layer 27 provided on the surface of the second sealing layer 26. This organic EL display device 1 is characterized in that a ratio of an SiN-group content to an NH-group content is higher in the first and third sealing layers 25 and 27 than in the second sealing layer 26 based on the absorption area ratio determined by FT-IR measurement.

Abstract: An organic EL display device 1 that includes a TFT substrate (substrate) 2 and an organic EL element (electroluminescent element) 4 provided on the TFT substrate 2 includes a sealing film 14 that seals the organic EL element 4. The sealing film 14 has a layered structure composed of an organic layer 14b and inorganic layers 14a, 14c. At least a peripheral portion 14b2 of the organic layer 14b has a lower carbon content than a central portion 14b1 of the organic layer 14b.

Abstract: A scanning line drive circuit includes a shift register having stages, hold circuits, and scanning signal output circuits. The hold circuit holds a shift register output in accordance with a sampling signal which is in an active level in one line period in a video signal period. The scanning signal output circuit outputs a scanning signal to be applied to scanning lines based on the shift register output, a hold output, a period specifying signal indicating whether it is in the video signal period or in a vertical flyback period, and timing signals. The scanning signal output circuit outputs a scanning signal for measurement and writing when the hold output is in a selection level in the vertical flyback period. It is possible to select a scanning line corresponding to the pixel circuits in one row and measure currents or voltages in the vertical flyback period, using a simple circuit.
