This question is very conflicting. But Yeah your question is very logical.
At the end of 1st meosis 1 polar body is formed by unequal division of 1° oocyte. the term unequal means .. The newly formed 2° Oocyte takes away a large amount of Cytoplasm with it and that why appear large, while on other hand 1st poler body get a very less portion of cytoplam and thus it don't have enough energy to initiate and complete the 2nd meosis.
