Abstract: A light-emitting element includes a casing including a recess, an LED chip disposed within the recess of the casing, and a sealing member permitting passage of light emitted by the LED chip and including a raised curved surface that is curved outward from the casing at an interface with a space external to the casing.

Abstract: A light-emitting element includes a casing that includes a recess, an LED chip disposed on a bottom surface of the recess of the casing, a sealing member to close the recess and permit passage of light emitted by the LED chip. The sealing member includes an interface with a space external to the casing, the interface includes an inclined portion at least at a peripheral edge portion of the sealing member, and the inclined portion gradually approaches a bottom surface of the recess as the inclined portion gets farther away from an optical axis of the LED chip.

Abstract: There is provided a video display apparatus the display screen of which is configured by combining a plurality of video display units in each of which light emitting display elements are arranged in a matrix manner; in the video display apparatus, there is provided a luminance correction means that corrects the luminance of video data situated in a correction subject area including respective end regions, of a first video display unit and a second video display unit, that face each other, in accordance with the spacing between the first video display unit and the second video display unit; and a linear noise that is caused at a seam portion between the video display units is suppressed, whereby the image quality of a video to be displayed can be raised.
