Display Panel Structure with a Light Emitting Unit Shielding Structure

Abstract

A display panel structure is provided, which includes an upper substrate, a lower substrate, a light emitting unit, a desiccating device, and a shielding structure. The light emitting unit is disposed on the lower substrate and between the upper substrate and the lower substrate. The desiccating device is disposed close to the light emitting unit. The shielding structure is disposed on the light emitting unit and between the desiccating device and the light emitting unit. The shielding structure has a width greater than the width of the desiccating device on the upper surface of the light emitting unit. The shielding structure includes a first shielding layer and a second shielding layer. The hardness of the second shielding layer is greater than the hardness of the first shielding layer.
