Problems solved by technology

For example, in conventional display devices, the aperture ratio of the display panel may be reduced in the process of limiting the light emission angle of the display panel, resulting in a decrease in luminance. Therefore, in order to achieve high luminance, there is a problem of increased power consumption.
In addition, conventional display devices have a problem that their lifespan decreases as power consumption increases.

Abstract

A display device is provided. The device includes a plurality of first electrodes electrically connected to pixel circuits disposed on a substrate; a pixel defining layer defining a plurality of opening regions, each of the opening regions exposing a portion of each of the first electrodes; a plurality of light emitting layers respectively disposed on the first electrodes in the opening regions; a second electrode covering the light emitting layers and the pixel defining layer; an encapsulation layer disposed on the second electrode; and a plurality of light blocking patterns disposed on the encapsulation layer between the opening regions adjacent to each other in a first direction.

Description

technical field [0001] The invention relates to a display device. Background technique [0002] With the development of the information society, demands for display devices for displaying images are increasing in various forms. For example, display devices are being applied to various electronic devices such as smart phones, digital cameras, notebook computers, navigation, and smart TVs. [0003] The display device can be applied to an instrument panel of an automobile, a center fascia (center fascia), or a center information display (CID: Center Information Display) arranged on a dashboard (dash board). Although such a display device can secure a viewing angle using viewing angle technology, a film that restricts the light exit angle may be used for security reasons or for improving image reflection phenomena as needed. For example, in a conventional display device, the aperture ratio of the display panel may be lowered in the process of limiting the light emission angle ...
