Abstract: A foldable display device includes a display panel, a protective base disposed on a top surface of the display panel, a polarizing plate disposed on a top surface of the protective base, a light blocking layer disposed at an edge of a top surface of the polarizing plate, and a hard coating layer for covering the polarizing plate and the light blocking layer and including a UV absorbent.

Abstract: A foldable display apparatus includes a display panel including a folding area and a non-folding area, the folding area configured to fold about a folding axis, a first lower retardation layer on the display panel, a second lower retardation layer between the display panel and the first lower retardation layer, a linear polarizer disposed on the first lower retardation layer, the linear polarizer having a polarization axis of 45±5° or 135±5° with respect to the folding axis of the display panel, and a window member on the linear polarizer.

Abstract: Disclosed is a sensor holder for an intraoral X-ray sensor including a front surface receiving incident x-rays, a rear surface, and a fastener, including a coupler including a grip fitted over a side surface of the fastener to enclose the same, and a support connected to the grip and facing in a forward direction of the intraoral X-ray sensor while covering the rear surface and a side surface of the intraoral X-ray sensor, a connector connected to the support and extending in the forward direction of the intraoral X-ray sensor, and a handle connected to the connector, wherein the coupler is made of a synthetic resin material with a first hardness (L1), and at least one of the connector and the handle is made of a synthetic resin material with a second hardness (L2) greater than the first hardness.
