LearningExperienceDesign.com describes Learning Experience Design (LX Design) as, “the process of creating learning experiences that enable the learner to achieve the desired learning outcome in a human centered and goal oriented way.”
This page from sixredmarbles.com takes a more utilitarian approach, explaining that LX Design is “a synthesis of instructional design, educational pedagogy, neuroscience, social sciences, design thinking, and UI/UX”.
