The organic EL display panel includes a substrate, pixel electrodes above the substrate, banks in gaps between the pixel electrodes, and a first and a second light emitting layer. A film thickness of the first light emitting layer is thicker than that of the second light emitting layer. The bank is provided with a first and a second bank portion, a height of the first bank portion being higher than a height of the second bank portion. A first pinning position where a sidewall of the first bank portion contacts with the first light emitting layer is higher than a second pinning position where the sidewall of the second bank portion contacts with the second light emitting layer.

Abstract: A transistor includes a gate electrode, an oxide semiconductor film, and a gate insulating film. The oxide semiconductor film includes a channel region and a low-resistance region. The channel region faces the gate electrode. The low-resistance region has a resistance value lower than a resistance value of the channel region. The gate insulating film is provided between the oxide semiconductor film and the gate electrode, and has a first surface located closer to the oxide semiconductor film and a second surface located closer to the gate electrode. The first surface of the gate insulating film has a length in a channel length direction which is greater than a maximum length of the gate electrode in the channel length direction.

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: An organic electroluminescence (EL) display panel includes a substrate; a plurality of organic EL elements; and a sealing layer in this order. In the organic EL display panel, the sealing layer has a three-layered structure in the order of a first sealing layer, a second sealing layer, and a third sealing layer. In the organic EL display panel, the first sealing layer, the second sealing layer, and the third sealing layer each include amorphous silicon nitride. In the organic EL display panel, when composition of the first sealing layer, composition of the second sealing layer, and composition of the third sealing layer are each indicated as SiNx, a value of x in the composition of the second sealing layer is greater than both a value of x in the composition of the first sealing layer and a value of x in the composition of the third sealing layer.
