Abstract: A display device includes: a base layer including a display area including an emission area and a non-emission area adjacent to the emission area, and a non-display area around the display area; a light emitting element in the emission area on the base layer; a color filter layer located above the light emitting element; and a light blocking pattern on the light emitting element and including a first light blocking pattern in the non-emission area and a second light blocking pattern in the non-display area. The first light blocking pattern and the second light blocking pattern are different in thickness from each other.

Abstract: A substrate processing method is provided. The substrate processing method comprises loading a substrate onto a substrate support inside a chamber, forming a plasma inside the chamber, providing a first DC pulse signal to an electromagnet that generates a magnetic field inside the chamber and processing the substrate with the plasma, wherein the first DC pulse signal is repeated at a first period including a first section and a second section subsequent to the first section, the first DC pulse signal has a first level during the first section, and the first DC pulse signal has a second level different from the first level during the second section.

Abstract: Provided are a method for preparing chiral nitro derivatives using organic chiral catalyst compounds and water as an eco-friendly solvent, and the like. The catalyst is an organic catalyst based on (R,R)-1,2-diphenylethylenediamine (DPEN), and can prepare nitro derivatives having enantioselectivity and diastereoselectivity in excellent yield through a hydrophobic hydration effect. In particular, the preparation method of the present disclosure can stabilize a transition state through an interfacial reaction between the catalyst and water. In addition, indole derivatives can be synthesized using the chiral nitro derivatives prepared according to the present disclosure to be usefully used for the prevention or treatment of brain-nervous system diseases including depression and muscular diseases including cachexia.

Abstract: Provided are a method for preparing chiral maleimide derivatives using (R,R)-1,2-diphenylethylenediamine (DPEN)-based organic chiral catalyst compounds and water as an eco-friendly solvent, and the like. It is possible to prepare chiral maleimide derivatives having high enantioselectivity even with a small amount of catalyst in an excellent yield within a short time. In particular, the preparation method of the present disclosure can stabilize a transition state through an interfacial reaction between the catalyst and water. In addition, spironolactone derivatives are synthesized using chiral maleimide derivatives prepared according to the present disclosure to be usefully used for the treatment of edema control, heart failure, liver cirrhosis, electrolyte abnormalities, hypertension, etc.

Abstract: A substrate coupling structure for a flat panel variable visual display monitor may be constructed with a guide rib, formed on the inside surface of a rear monitor cover, having a race for receiving two adjacent edges of a rectangular substrate (PCB); and a plurality of elastic snaps, formed on the rear cover opposite the guide rib, each having a catch for receiving the other two edges of the substrate, thereby enabling the substrate to be securely coupled to the rear cover.

Abstract: A flat-display panel monitor discharges excessive heat generated by its main PCB using an air duct and a fan to force air through the monitor housing. This allows for greater cooling than that naturally occurring through convection. The apertures in the monitor are also covered with filters to reduce the level of contaminants that enter the monitor's housing.

Abstract: A video printed circuit board is mounted on a slotted holder which closely receives the neck of a CRT and has a plurality of circumferentially-diverged apertures which receive projections extending from a circumscribing elastic band that compresses the holder, the projections frictionally engaging the neck.
