The disclosure provides a display panel and a display device. The display panel includes a display substrate and a lens structure. The display substrate includes a plurality of light-emitting devices and a receiving layer located on light-emitting sides of the light-emitting devices. The lens structure is located on the receiving layer and includes a plurality of lens units, and the lens units are arranged in correspondence with the light-emitting devices. Each of the lens units includes a color blocking layer configured to absorb light in ambient light that is different in color from light emitted from a corresponding light-emitting device. The lens unit has a refractive index greater than a refractive index of the receiving layer.

A display apparatus including an oxide semiconductor is provided. The display apparatus includes a driving circuit and a light-emitting device on a display area of a device substrate. The driving circuit can be electrically connected to the light-emitting device. The driving circuit can include at least one thin film transistor. A semiconductor pattern of the thin film transistor can include an oxide semiconductor. The display area can be surrounded by a barrier line. The barrier line can include a hydrogen blocking material. A barrier trench can penetrate inorganic insulating layers stacked on the barrier line. A cover pattern can be on a side-wall of the barrier trench. Thus, in the display apparatus, the movement of hydrogen from an edge of the device substrate toward the display area can be blocked. Therefore, the degradation in the reliability of the driving circuit due to the penetration of the hydrogen can be prevented.
