Embodiment Construction

[0033] The present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described exemplary embodiments of the present invention may be modified in various different ways, all without departing from the spirit or scope of the present disclosure.

[0034] Throughout the specification, it will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. Also, in the specification, the word "upper" means placed on or below the object portion, and does not necessarily mean placed on the upper side of the object portion based on the direction of gravity.

[0035] Additionally, unless expressly stated to the contrary, the word "comprise" and variations thereof will be understood to imply t...

Abstract

A disclosed photosensor includes: a first electrode layer including a reflection part having an inclination surface; a first semiconductor layer positioned on the first electrode layer; a second electrode layer positioned on the first semiconductor layer; and a first dielectric layer and a second dielectric layer sequentially positioned on the second electrode layer, wherein the first dielectric layer and the second dielectric layer have different dielectric constant values. Further, the disclosed display device includes a plurality of pixel areas positioned on a substrate, and a sensor unit formed in at least some pixel areas among the plurality of pixel areas.

Description

technical field [0001] The described techniques of this disclosure generally relate to light sensors and display devices that include light sensors. Background technique [0002] Light sensors are commonly used in display devices for functions such as user reaction detection, ambient light detection, document scanning, and fingerprint scanning. However, even if the photo sensor is included in the display device, since the conventional photo sensor has low light-sensing efficiency, the functions described above cannot be smoothly performed. Therefore, it is difficult to directly apply the functions described above to a display device. Contents of the invention [0003] The present disclosure provides a photosensor having excellent light-sensing efficiency and a display device including the photosensor. [0004] The present disclosure provides an optical sensor including: a first electrode layer including a reflective portion having an inclined surface; a first semiconduct...
