Abstract: An organic light-emitting panel includes a reflective electrode, a functional layer, having a single or multi-layer structure, located on the reflective electrode, an organic light-emitting layer located on the functional layer, a transparent electrode located above the organic light-emitting layer, a low refractive index layer located on the transparent electrode, and a first thin-film sealing layer located on the low refractive index layer. The low refractive index layer has a lower refractive index than both the transparent electrode and the first thin-film sealing layer. Difference between respective refractive indices of the low refractive index layer and the transparent electrode is 0.4-1.1. Difference between respective refractive indices of the low refractive index layer and the first thin-film sealing layer is 0.1-0.8. The low refractive index layer has thickness of 20-130 nm.

Abstract: A gate driver IC (i.e., gate driver circuit), when set to a first mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with one clock cycle of a clock inputted to the terminal CLK** (clock input terminal), and outputs a selection voltage or a non-selection voltage based on a data position in the gate driver IC; and when set to a second mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with n clock cycles (n is an integer of at least 2) of a clock inputted to the terminal CLK**, and outputs the selection voltage or the non-selection voltage based on the data position in the gate driver IC.

Abstract: A current limiting circuit is used in a display device which includes a display panel having pixels each of which includes a light emitting element and a panel power source which supplies an application voltage to be applied to each of the light emitting elements included in the pixels. The current limiting circuit detects a supply current supplied from the panel power source to the display panel, and reduces the application voltage when a value of the supply current detected is greater than a threshold.

Abstract: Organic light-emitting device manufacturing method performed by using a manufacturing apparatus placed where light from outside is blocked and a lighting device emitting light constituted of light components with wavelengths of 500 nm or longer is placed. The manufacturing apparatus includes a main body having an ejector ejecting ink containing organic light-emitting material and a light-transmissive tube forming at least part of a transport path connecting a tank containing the ink and the ejector. The method includes: removing the ink inside the transport path when a total exposure amount ET (lux×hours) satisfies ET≥α×17500 where α is a constant satisfying α≥1. ET is a product of E denoting light amount (lux) from the lighting device to which the tube is exposed and T denoting time amount (hours) over which the tube is exposed to the light from the lighting device.
