  • Publication number: 20250008826
    Abstract: A display device includes sub-pixels corresponding to sub-pixel areas. Each of the sub-pixels includes a display unit including a light-emitting layer which emits light, and a reflection control layer disposed over the sub-pixel areas on the display unit, where the reflection control layer selectively absorbs light in a wavelength band. The reflection control layer includes a first layer and a second layer disposed on the first layer, where the second layer has a thickness less than a thickness of the first layer. The second layer includes a liquid repellent material.

  • Publication number: 20240293331
    Abstract: The present invention relates to a composite formulation for oral dosage that comprises an API selected from 1-(3-cyano-1-isopropyl-indol-5-yl)pyrazol-4-carboxylic acid or a pharmaceutically acceptable salt thereof and does not comprise a pH modifier as an excipient. Since the composite formulation for oral dosage according to the present invention does not comprise a pH modifier, it has the advantage of having a high level of dissolution rate as well as enhanced dosing convenience and productivity, in spite of comprising a high content of API.

  • Publication number: 20240216331
    Abstract: The present invention relates to a composite formulation for oral administration comprising an active pharmaceutical ingredient (API) selected from 1-(3-cyano-1-isopropyl-indol-5-yl)pyrazol-4-carboxylic acid or a pharmaceutically acceptable salt thereof, wherein the API has a particle size of granules corresponding to 90% of the maximum particle size in the cumulative particle size distribution (D(0.9)) of 80 ?m or more and 300 ?m or less. The composite formulation for oral administration according to the present invention has a low friability and an increased dissolution rate even if a high content of API is included, by regulating the particle size of the API to a certain range.
