According to the present invention, a stack comprises, between a carrier substrate and a flexible substrate layer, a peeling power adjustment layer comprising polyimide, which has a refractive index higher than that of the flexible substrate layer, so that a flexible substrate can be more easily peeled from a carrier substrate layer, and thus a flexible element can be manufactured without damage to the element through a simpler process.

Stack for manufacturing flexible element and method for manufacturing flexible element by using same

The present invention relates to an isoindolin-1-on derivative, a method for preparing same, and a pharmaceutical composition comprising same as an effective component for preventing or treating tumors, wherein the isoindolin-1-on derivative exhibits a high inhibitory effect on EGFR mutations, and thus can be beneficially used for the treatment of EGFR-mutated tumors, and the isoindolin-1-on derivative exhibits a significant synergistic effect when co-administered, and thus can be beneficially used in concomitant therapy.

The present invention employs a polyimide film, which has a coefficient of thermal expansion (CTE) that is a negative number at a temperature equal to or greater than 350&#xb0; C., as a debonding layer for separating a flexible substrate and a carrier substrate, and thus can easily separate a flexible substrate from a carrier substrate by using a detaching phenomenon caused by a difference in residual stress between the flexible substrate and the debonding layer after a high-temperature process for producing an element on the flexible substrate. Therefore, the present invention can separate the flexible substrate without causing chemical or physical damage to the element formed on the flexible substrate, thereby minimizing problems that may occur during a stripping process.

Laminate for manufacturing flexible display, and flexible display manufacturing method using same

The present invention relates to a N2,N4-diphenylpyrimidin-2,4-diamine derivative, a method for preparing the same, and a pharmaceutical composition for the prevention or treatment of cancer, containing the same as an active ingredient. The derivative shows a relatively weak EGFR activity inhibitory effect on wild-type EGFR, a high inhibitory ability on EGFR mutation, and a high inhibitory ability on even FLT3 and FLT3 mutation, and thus, can be effectively used for the treatment of cancer with EGFR mutation or cancer with FLT3 or a mutation thereof, and the derivative shows a synergy effect at the time of combination administration, and thus can be effectively used for the treatment of combination administration.
