摘要： An ink drying process includes exhausting gas from atmosphere surrounding a substrate and drying ink through placing the substrate in a predefined pressure or less to form organic functional layers. Exhausting of gas includes: reducing, during a first period, pressure of the atmosphere from standard atmospheric pressure to a first pressure higher than vapor pressure of solvent having the highest vapor pressure among solvents of the ink; and subsequently reducing, during a second period, the pressure of the atmosphere to a second pressure lower than vapor pressure of solvent having the lowest vapor pressure among the solvents. Where pressure of the atmosphere is 10x Pa (X indicating a real number), a change amount average of X per unit time has a greater absolute value during the second period than during the first period.

摘要： A method of manufacturing an organic electroluminescence display panel includes forming pixel electrode layers in a matrix on a substrate. The method includes arranging column banks extending in a column direction above the substrate. The method includes applying ink containing organic light emitting material to gaps between the column banks so that the ink is continuous between ends of the column banks in the column direction. The method includes arranging the substrate and a rectifying plate facing each other, the rectifying plate having a uniform density of through holes, such that the rectifying plate is at a predefined distance from the column banks. The method includes exhausting gas from an environment including the substrate and the rectifying plate. The method further includes heating the substrate to dry the ink to form an organic functional layer. The method includes forming a counter electrode layer above the organic functional layer.

摘要： A display apparatus includes a display panel and a driving circuit. The display panel includes signal lines extending in a column direction, scanning lines extending in a row direction, and lead-out lines extending in the column direction. Each of the lead-out lines intersects with corresponding one of the scanning lines at an intersection and is electrically coupled to the corresponding one of the scanning lines at a node. The node is disposed at the intersection or in a region surrounding the intersection. The driving circuit supplies corresponding one of the signal lines with a signal pulse corresponding to an image signal, and supplies corresponding one of the lead-out lines with a selection pulse having a peak value based on a distance from one end of the corresponding one of the lead-out lines to the corresponding node, after increasing the peak value with an increase in the distance.

摘要： An organic EL display panel including pixels arranged in a matrix includes: a substrate; pixel electrodes arranged above the substrate in the matrix; an insulating layer provided above the pixel electrodes and having openings for each pixel electrode; banks extending in a column direction and partitioning between the pixel electrodes in a row direction; organic functional layers provided above the pixel electrodes and including organic light emitting layers where organic electroluminescence occurs in the openings; and a light-transmissive counter electrode provided above the functional layers. The openings include: first openings arranged in line in the column direction; and a second opening adjacent to one of the first openings in the row direction. Portions of the insulating layer between the first openings adjacent in the column direction are lower in height relative to the pixel electrode than a portion of the insulating layer between the first opening and the second opening.
