摘要：
A display panel includes a first substrate, a light-emitting component located on the first substrate, and an encapsulation part located on the first substrate. A receiving cavity is formed between the encapsulation part and the first substrate. The receiving cavity has a light-emitting region inside. The light-emitting component is located within the light-emitting region. The display panel further includes at least one water vapor detecting part located on the first substrate and inside the receiving cavity. The at least one water vapor detecting part is disposed outside the light-emitting region. Each of the water vapor detecting part has different light transmittance before and after water absorption.
